It's hard for me to give you a definitive answer because I can't access the page as its rendered in your environment. However, the SPAutocomplete function (like all of the value-added functions in SPServices) look for specific elements in the page based on what SharePoint is expected to render. Your markup is undoubtedly different.
You might also consider using jQueryUI's autocomplete function, feeding the data to it using GetListItems calls.
