After the form is created you can rename the elements to work with your pearl script.
as for the validation, did you uninstall validation toolkit before installing css form builder?
are you using client or server side validation?
can you send a sample of one of the pages you cannot apply validation to?
A screen shot demonstrating the problem would be helpful as well.
So the file does not need a PHP extension for the validation to work?
Yes I uninstalled validation toolkit, which of course always recognized every form and form element on a page no matter how it was named.
I am using client-side validation.
I will send a sample form that will not validate in a few days.
