I guess I still haven't completely figured out the file structure in Zen Cart! Please point me in the correct direction.

The problem? I've set up an elaborate custom contact form through the Define Pages Editor (../includes/template/my_template/tpl_contact_us.php) but find that the standard contact form appears at the bottom of the form. I'd like to use my form in place of the standard one but haven't been able to find the file that generates the standard form.

What file contains the default form for the contact us page?

Thanks,

Jim
