jQuery Grid Plugin - jqGrid

Again, this used to work in earlier versions (although I suspect this is more of a question about jQuery than jGrid -- sorry about that; I hope someone knows the answer anyway)

    $("#fullpage_txtclientvendor").autocomplete("url here" {
        delay: 150,
        width: 260,
        max: 25,
        autofill: true,
        selectFirst: true
      });
    $("#fullpage_txtclientvendor").result(function(event, data, formatted) {
        $("#fullpage_txtclientvendorkey").val(data[1]);
      });;

The error I get refers to the second statement: $("#fullpage_txtclientvendor").result(function(event, data, formatted) {

Any help would be greatly appreciated

Thanks
