hi am new to jsp
i hav a situation
i hav a listbox
it contains 4 values [s,a,r,d]
the moment s value is selected from the list 4 fields will be unlocked
what i want is
i want the listbox to display only one value[s] if the 4 fields which are unlocked are not filled in by the user
if he has filled in all the 4 fields then all the 4 values of the listbox should be displayed
how can i achieve this
thanks in adv
