Custom footprint and publication forms

So I created a custom platform configuration file to identify a form on gumtree.co.za. It's like a craigslist site. When I run the poster, you can only identify the form but you can not publish anything. Here is my code;

[setup]
FriendlyName = Gumtree contact form
Platform = Contact form

PageMustContain = sending a copy
PageMustNotContain =

Footprint = & # 39; Message & # 39; & # 39; Name & # 39; & # 39; Email & # 39; & # 39; Phone & # 39; & # 39; Log in to enable sending a copy to your email & # 39;

Success =

Your message has been sent

Failure = required

Markup = HTML
UseBlackList = 0
UseWhiteList = 0

[STEP]
FormMustContain = class = "replyAd"
FormMustNotContain = id = "searchform" | class = "searchform"
buyerName =% rnd-name%
email =% rnd-email%
replyMessage =% rnd-comment%
phoneNumber =% rnd-website%
machineId =% ignore%
rand =% ignore%
fileName =% ignore%
adId =% ignore%

Where could I be making an error?
