Hi Guys,

Its my first post here, and hoping to find some help..

I have installed a spiderPoll v1.1 system on my server, the problem is I cant seem to be able to vote.. It displays everything correctly but when I try and vote it will not recognise my vote..

Here comes the code:

Poll.php

Poll.txt

HTML is my favorite language.:0|JavaScript is my favorite language.:0|Perl is my favorite language.:0|PHP is my favorite language.:0

The file ips.txt is currently empty..

I have also set file premissions for poll.txt and ips.txt to 666.

You could have a look at the poll here: https://w1185677.users.ecs.westminster.ac.uk/factor/poll.html

Guys any help with this would be greatly appreciated..

Thank you for your time.. :)
