jQuery issue in Internet Explorer 8

I am trying to get my jQuery functions to work on IE8. I am loading the library from Google's servers (http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js). The `$(function(){})` is never called. Instead, I get an error `Object expected`. I opened the developer and ran `typeof $` in the console, and it came up as `undefined`. I have tried going to other sites that I know use jQuery (jquery.com), and those all work, is there something I might be missing here?
