Here is the code. IE7 spouts an "'active.0' is null or not an object" error on line 39, which is:
input.trigger("activate.autocomplete", [$.data(active[0], "originalObject")]); $("body").trigger("off.autocomplete");
Works perfectly in Firefox/Chrome/Opera. Any ideas? Many thanks and much appreciated.
