Dynamics CRM forms: jScript for a dummy

Breaking my head against more compex problems, I try to get back to basics.

I want to have a jScript in a form, that upon user change i开发者_C百科n control Sub-Fund, will pop up a message showing the new value of that control.

Here is my code -- which returns an error, of course 8-(((

function TestForDummy()
{
   var noind = crmForm.all.new_subfundid.DataValue;
   alert(noind);
}

Whenever I update Sub-Fund, it gives me an error

Field:new_subfundid, Event:onchange, Error:Object expected

What'wrong ?

Try this :

function TestForDummy() 
{ 
    var lookupValue = Xrm.Page.getAttribute("new_subfundid").getValue();   
    var noind = lookupValue[0].id;
    alert(noind); 
}
