FormNumber -1 works, but Form# 0 doesn't work, why?

[bluescharp]

There is only one form in the page, when I set Form# to -1, ZP works. but when I set Form# to 0, ZP says "Not a single element with the specified parameters is found".

Usually pages have several forms.
-1 means ALL forms.
Use -1 and Zennoposter will look for element within a whole page.

Form# all begin with 0, is that right? When there is only one form, I think Form # -1 == Form #0, but Form #0 doesn't work, why?
This is important to me because I have to determine the exact number of Form in my template.

Thanks.

If form # 0 doesn't work that means that element is not presented in this form.
Use -1 to look for in all forms. That's usually the easiest way.

form #0 is form 0
form #-1 is the 1st form that match

form -1 is all forms at a time
