Hiya Diana,
No problem, I'm afraid (sadly) that this constitutes 'fun' for me. :(
I have done a mish-mash of yours and my files, to get the functionality, and just need to get the styles finished.
Hopefully you will just need to drop the contactus.php & thankyou pages and a CFSP folder in to your site, put your email address in the WA_Globals.php file and upload. I will need to send this privately, as the files are pretty much all the CFSP and this is a public forum. It is easier that way than sorting out all the separate bits.
Drop me an email: neil [at ] yeractual [.] com , or send one via my demo form page.
