Hi,
I have made wonderful captcha, but I need to know how do I do the checking?
The text in the captcha is $captchacode, and I need to check wheather it is the same than what usertyped. But how do I do that? If user types the captcha and presses Submit, then the $captchacode variable will be unset??
