form validation: select and checkbox

[lucesei]

Hi,
I'm looking for a script that:
1) verifies that a select option has been chosen
2) at least 1 checkbox has been ticked

My checkboxes are generated dinamically with PHP, so the number varies...

Can anyone help?

Thanks and bye

Here are some general scripts for validating all controls. Maybe they will help:
