I have suggested to our sales department that a statement be added to that page saying that the contact form is not an extension.
Can you describe the problem you are having getting the contact form to work?
I will be able t offer assistance in getting it to work once I have an understanding on the specifics of the problem you are experiencing.
As Neilo said, after changing the WA_Globals.php file, the contact from will need to be uploaded to your remote host.
Can you provide a link to the contact form.
When you open the contact form in a browser, do you get an error message?
If not, after filling in the entire form, and clicking the submit button, does it direct to the thankyou.php page?
