I am Adding webscript in my alfresco-4.2.f, but when I refresh websript then it gave  me error?

Probably your web script description file has an error. But you provide too few informations about your script for successfully analysing it..

Martin see the script ----

<script type="text/javascript">
new Alfresco.widget.DashletResiz("${args.htmlid}","${instance.object.id}");

var helloWorldDashlet = new Alfresco.dashlet.HelloWorldDashlet("${el}").setOptions(
{
componentId: "${instance.object.id}",
greeting: "${greeting}",
user: "${user}"

});

var helloWorldDashletEvent = new YAHOO.util.CustomEvent("onConfigClick");
helloWorldDashletEvent.subscribe(helloWorldDashlet.onConfigClick, helloWorldDashlet, true);

new Alfresco.widget.DashletTitleBarActions("${args.htmlid}").setOptions(
{

actions:
{
{
cssClass: "edit",
eventOnClick: helloWorldDashletEvent,
tooltip: "${msg("dashlet.edit.tooltip")?js_string}"
},
{
cssClass: "help",
bubbleOnClick:
{
message: "${msg("dashlet.help")?js_string}"
},
tooltip: "${msg("dashlet.help.tooltip")?js_string}
}
}

});
</script>

Error is that -- el expression is not defined.Can you suggest me ---

How to implement it?
