My first poll -> cookie problem

[Atari]

I wrote this poll wich I wanted to protect from voting twice. But it doesnt work. Visitors still can vote multiple times. I attached the script. The problemfile is ontwerppoll.php It's very simple but it doesnt work! It's driving me mad!

When using the [man]cookie()[/man] function then you have to set the time when it will expire. If you do like you've done it now, it's called a "session cookie". It will expire as soon as the visitor closes their browser. Try something like this instead:

setcookie("stemmen","ja",time()+3600)

This cookie will expire after one hour.
