I'm pulling my hair out because I can't get a friggin alert to pop up when I click a link. I've been working with JQuery, so that may have something to do with it.

There are multiple external .js files that my primary .php file references. What determines if one .js file takes presedence over another? How do I directly reference a specific bit of .js code for an individual html element? I'm not sure why this crap isn't working.
