jquery autocomplete rendering hidden div

I have been trying to get jquery.autocomplete (http://docs.jquery.com/Plugins/autocomplete) to work for the last few hours and can't get past this issue. It keeps rendering a hidden div con开发者_如何转开发taining the ul. Can anyone tell me what I'm doing wrong? The ul contains the appropriate data....

Thanks, Mike
