Hi Robert,
>> Is there a problem with forms on form?
yes, absolutely. You can't embed a form in a form, because that would result in an html <form> tag inside another <form> tag, and HTML doesn't allow that.
The best you can do is put a button on a form, which in turn links to another (popup) form.
I may change this around in the future a bit, but for now it's a very definite limitation.
cheers
Bruce
