My implementation of jquery.jsonSuggest.js works for me in Firefox, but it's not working in IE7.

I know it works in IE7, b/c the demo site works in IE7.  What am I doing wrong/differently that's causing my implementation to not work in IE7.

Here's my implementation:  http://qa.chiefsupply.com/suggest1.asp

Here's the demo:  http://tomcoote.co.uk/JavaScript/JSONSuggestBox/demo.html

Thanks in advance!!!!
