$(document ).ready() doesn't work

I’m running a wordpress configuration on my local computer using iis7. The jquery file is being loaded properly. I checked by going into the page source and clicking on the include link. It populates with the jquery source code fine. The problem i am having is that it doesn’t seem to trigger $(document).ready(function). I tested this by creating the ready function and just putting an alert box inside. Doesn’t work. I’m looking for any suggestions. Thanks in advance.
