Drop down not getting populated for IE 7.0

It will be hard to assist without seeing some sourcecode how you try to do it.

I am having 2 drop down boxes .One for selecting country and another for selecting states of that country.
When i select a country in one drop down box ,corresponding states are getting populated in second drop down box.I am making use of XMLHTTPRequest.This is working fine for IE 6.0.
But this is not working for Mozilla and IE 7.0
