adding a captcha element to pre existing form
i've read but don't understand the document(s) for editing a form.
I have a form created by FB, and now want to add one more element to the form, a captcha field. There is no current validation of any of the fields, either server or client side.
I opened the FB WA->...Insert Form, chose <New From Blank> edit, Group 1 edit etc.
Is FB expecting to see an image element somewhere on the form so that it can interpret
that image element as a captcha? Or does it somehow add the captcha element itself
and then customize it somehow? From the CS4 dropdown there is no insert captcha element, so i am at a loss how to do this.
