JQuery :: Won't Load Fresh Content From PHP File?

I wrote a small script that animates, loads content from a PHP script into a div, then animates again. It works splendidly in firefox, but for some reason, in IE, it won't load fresh content from the PHP file, even if I reload the page. Given that the PHP works fine in Firefox (and I've tried clearing variables in it),[code]I realize this looks odd, but another strange quirk is that it won't load the content when I first load the page unless both of the functions are written that way. Maybe if you have a suggestion to clean up the code as well, I could implement it.
