How Do I Return An Array From My Query?

Question

I have the following query that does not complete and I receive an error:

on(dom.byId("btnSupportNext"),"click",function(){
            console.log("Next Works");
            var query = new esriQuery();
            var queryTask = new QueryTask(config.signLayerUrl);

query.where = "SUPPORTID = " + document.getElementById("supportId");
            queryTask.execute(query,function(results){
                console.log(results);
            })

The latest github code is here: csergent45/streetSigns at 754f9558a6a37e1e8a825b860e781d9ea4e4ba3d · GitHub

And I have re-published the application here: Street Signs
