## How do I make formulas effective only starting from tomorrow in Google Sheets?

I made a google sheet for insulin-dependent diabetics, to calculate insulin units based on their meal content and glucose reading inputs. Each day has its own block of cells for the patient. When I edit the governing formulas in another sheet called ‘factors’, how do I make them effective starting from tomorrow, leaving previously calculated cells unchanged, to get back to as a history?

Here is the formula I’m using in a C5 calculating cell:

=if(C4=””,””,(C4-factors!C\$7)/factors!C\$5+C3/factors!C\$3)

And Here is an example of the sheet

## formulas – Google Spreadsheet: Adding together multiple Sum Filter or Sumifs with multiple conditions across multiple sheets?

So I have a budgeting spread sheet. I have an overview page that I need to link to a “Checkings” sheet and a “CC-Chase” sheet.

To calculate the amount spent on a specific category that month I currently use:
`=sum(filter(Checkings!\$B:\$B,Checkings!\$C:\$C=("Grocery"),Checkings!\$A:\$A>=("1/1/21")+0,Checkings!\$A:\$A<=("1/31/21")+0))`

I want to add in the same data from my credit card statments so I tried:
`=sum(filter(Checkings!\$B:\$B,Checkings!\$C:\$C=("Grocery"),Checkings!\$A:\$A>=("1/1/21")+0,Checkings!\$A:\$A<=("1/31/21")+0))+(FILTER('CC-Chase'!\$F:\$F,'CC-Chase'!\$D:\$D=("Grocery", 'CC-Chase'!\$B:\$B>=("1/1/21")+0,'CC-Chase'!\$B:\$B<=("1/31/21")+0)))`

But this gives me an error. I’ve tried a few other combinations of this but always get an error.

Does anyone know what I’m doing wrong or have another way I could do this?

## formulas – Combine multiple IF statement/condition into one google sheet column

If it were up to me, I would not setup your sheet the way it is. But as you have things set up, try this formula in B8:

`=ArrayFormula(IFERROR(VLOOKUP(B7&B9,{A2:A5&C2:C5,B2:B5;A2:A5&E2:E5,D2:D5},2,FALSE),"NO MATCH"))`

The formula uses curly brackets to form a virtual array with the A2:A5 values concatenated with C2:C5, and to the right of that (in memory), the values from B2:B5. Underneath this array (as denoted by the semicolon), another array is formed with the A2:A5 values concatenated with the E2:E5 values this time, and to the right of that (in memory), the values from D2:D5. In the end, this array will contain just two columns: the first with the concatenations of every rows model with each possible vendor for that model, the second with the correlating size for that pairing.

The `VLOOKUP` then concatenates your selected model and size from B7 and B9 and looks for it in the virtual array above. If that combination is found, the value in column 2 of the virtual array will be returned. If it is not, the `IFERROR` will return “NO MATCH.”

The `FALSE` in the `VLOOKUP` means “My results aren’t in perfect ascending order and I’m looking for an exact match only.”

## Google Sheets – existing row formulas are being erased after google form submission

I am having problems with Sheets and Forms connection.

I have pre-entered formulas on Google Sheets, like vlookups and TO_DATE value, but as soon as I submit entries from Google Forms, the formulas that I typed in before were erased and the cells are now blanks.

Form–

• Employee ID
• Time Log
• Remark

SheetA–

• Timestamp
• Employee ID
• Time Log
• Remark
• Date – To_DATE value from Timestamp
• Full Name – vlookup from SheetB

## dnd 5e – Are there formula’s for Warforged Armor? (Proficiency + Dex + 11 =AC)

The WarForged have 3 separate armor types of which from UA, that determine their AC, as armor has no effect on them nor does it stack. I was wondering if there was a Formula for me to utilize for the modifier section in the armor section below. Where it takes the current proficiency bonus and/or dex modifier (just PB for heavy armor) adds it to a number 11,13,16 and then determines my AC?

Formula like AC = dex + pb + number

This is on ROLL20 GIFFGLYPHS

## google sheets – How to check duplicates by combing these formulas?

I am checking if column S is empty then i need to set a rule in a cell to make conditional formatting in cell A1
`=if(AND(\$Q\$9:\$Q="Consultation",\$S\$9:\$S=""),1,0)`

`Y9=SUM(X9:X58)`

`A1=Y9 >0` , a rule is applied.(conditional formatting custom formula)

The question is how to combine all these functions in one formula in conditional formatting/custom formula instead of depending on two results successively . Like Arrayformula

## Are those temporal logic formulas equivalent?

I am wondering whether those two formulas are equivalent:

This LTL formula:

$$AG(prightarrow Gq)$$

And this CTL formula:

$$AG(prightarrow AGq)$$

I thought that they are equivalent, however points were deducted when I wrote that they are (This was a yes/no question, so no explanation was needed).

What am I missing? Why are they not equivalent?

## formulas – Transposed data in google sheets

Hi I would like to re arange some data to be prepped for export. My input data is:

``````            Col1
Row 1 First L. 1A-123
Row 2 John D. 2B-123
Row 3 Ben A. 3C-123
``````

This data can contain values up to row 5 and should be able to be variable.
I would like the output data to look like this.

``````                    Col1
Row1 First L. 1A-123, John D. 2B-123, Ben A. 3C-123
``````

Noting that the Last value will not have a “, ” at the end.

Any Ideas on how I can reference the number of values and add/concatenate “, ” if there is another value left to add.
Thank you for any help

## formulas – How to use AND with a symbol instead of a function in Google Sheets?

I know that we can use the AND function to create conditions based off of more than one criteria:

``````=IF(AND(A2<>"", B2=""), "You are missing a last name", "")
``````

However, in SQL and programming we can specify AND with `&&` and OR with `||`. This makes expressions easier to parse, especially when you have a bunch of conditions chained together:

``````=IF(A2<>"" && B2="", "You are missing a last name", "")
``````

When I try the above, it shows the error:

Formula parse error.

Is there a symbol we can use for AND and OR instead of the functions in Google Sheets?

The reason I suspect there might be a symbol is because instead of `CONCATENATE`, they allow you to use the `&` symbol:

``````=CONCATENATE(A2, B2, C2)
``````

Is the same as:

``````=A2 & B2 & C2
``````

Thus I suspect there might be a succinct way to specify AND and OR conditions.

## formulas – Moving average google sheets

I’m looking for a way to calculate the average turnover of the past 4 weeks.

The formula I used to determine te current year/weeknumber is:

=year(now())&”_”&0&(WEEKNUM(now();21))

The current year/week is 2021_05.

So I’m looking for a way to adding up the values of:

2021_01 + 2021_02 + 2021_03 + 2021_04.

The number I’m looking for is the sum of these values (33.344 + 30.360 + 27.192 + 30.000) divided by 4.

Also the (moving) average should be excluded from zeros and empty cells.

Is there a way to calculate the average of the last 4 weeks in google sheets?
