look at my post…

however, i have made a few corrections to my post reference – as it was incorrect in describing how autocomplete works.

Look at my last post in that thread now: http://www.trirand.com/blog/?page_id=393/help/while-the-select-editoption-posts-the-value-or-id-of-the-selected-list-item-autocomplete-posts-the-label-i-need-id-posted/

and you will probably answer your own question.
