this line of your code:

Expand|Select|Wrap|Line Numbers
  1. var a=document.getElementById("cmbState3");
returns you a dom-node-reference (an object) to variable a in case the method finds the node in your doc ... otherwise a will be null ...

so you cannot compare a string with an object ... what do you really want to compare? any property or attribute of the node?

kind regards
