Ok, so I almost have this script finished, but I'm having an issue where I am getting an Undefined Index error when I try to submit the page on the 'site' index, used in both the $_GET to get it from the URL, and the submit.

So far you guys have been amazing with my other errors, I'm hoping you can point me in the right direction. And I know, I should use prepared statements, but I'm just learning how to do them now that I've been told what they are. I will fix that in due time. Right now, I just need to get this update page working.
Thanks.
