%capquest%

Doc say %capquest% can be both (captcha or question)

So, setting:

name=%capquest% 

How will ser redirect to captcha or question captcha ?  please give details

it extracts the text in front and back of the input field...checks if that is a question -> %question%

if there is an image between input fields, then it usually is a captcha

So it has several tests before deciding to use one or the other.
