Cookies are mad and behaving badly!

Dear Guru's. I have a big problem. Actually, it's very small - but greatly annoying, and highly critical to my site. I beg you for help, since I have been trying to get this darned thing working for a straight week, and cant really figure out what is wrong. Please take a look at this script: http://www.smartsmartsmart.com/downloads20.php3?Category=1 (The category parameter must be there, for demo purposes) Source code is attached. Voting for one of the files goes fine, however, when one tries to vote for the second file, the two other cookies (files) get reset. I have been pulling a lot of hair out on this one, and I'm desperate for help. The text in the file desription windows is what I've used for debugging - don't let it confuse you - the important thing is "votecookieXX equals X" That is what the respective cookie is set to. I amt that this is a great bit of help to ask for, but this list is my last hope. Please, please pretty please help! /Mattias
