Hi,

I have two listboxes. Both the list boxes contain the numbers from 1 to 10.

If I select 2 in the first select box and also 2 from the second select box i have to get the alert that both the select boxes should not contain the same value.

I need the script without submitting the form.

Can anyone help me out?
