Do you want the options in them to change when the value of the first changes?

I'm not understanding what you're asking.

hi The Hobo
thnx for ur time
I need to change the data of the two comboboxes dynamically...
for eg....
I have a combobox like this
<select name="example" multiple size=4>
one combo box has values...."Software","Hardware","Sales" etc
now if the user selects "Software" then the second comboxbox holds the value
"Client/Server Tech","Ecommerce/Intranet","Datacom"
and the third combobox has value a "Fresher","Trainer","Programmer"
similarly for the second values for the first combo box...
hope it was clear..
waiting for
your reply...
