Don't laugh. :(

It will soon be pretty obvious how new I am at this...

Here all I'm trying to do is get the "value" of an editbox, then increment it up by one.

What is wrong?

  <script language="Javascript">

               //change doXxxxx() to doAnythingElse() then change element events to same
        function doPlus() {
            var value = $("#Qty1").attr("value");
                        $("#Qty1").attr("value") = value++;
     } 
 </script>
