Well then, I suggest you start reading
From looking at the script a second time, I would suggest finding another one. There are a ton of poll scripts out there ( http://www.hotscripts.com/PHP/Scripts_a ... nd_Voting/
) and im sure if you looked long enough, you would even find one that is self-automated and has an installer.
In order to understand a script, you have to be able to understand programming. HTML and PHP are completely different, and they work differently.
