Hi Khaled

I can't see anything wrong with your code myself.

Are you using the Firebug extension in FireFox?  If not, it is great for 
inspecting the result of Ajax actions.  I use it to debug exactly this 
sort of issue.  It will let you see the select tag code and check that 
the values in the tag are being set correctly.

Regards,
Langdon
