i've got a script file which loads for my channel when i open MIRC, however this isnt a solution - i want to host the script files on my web server, so the quiz is always up and running
Running on your web server (so the person has to go there with a browser) or running in your channel?
If the first, you'd have to rewrite it in php or some other language that could run on a web server.
If the second, leave your mIRC running and connected 24/7.
