Index error in drop-down search field
Dear Support, I've created a Database Management system using Data Assist and the supplied BlueSkyMusic database. I've added search options on the results page. However when I am in the results page and I wish to do a search on a drop-down field say 'category' - the following appears in my drop-down "Notice: Undefined index ItemCatID in C:\wamp\www\sandbox\Results.php on line 275>CD." I have attached 'screenshots' of the results page and the relevant code for the field. Can you spot anything? Everything was generated by DataAssist.
