Validating User Selection for Combo Box

[Guest]

I have a form which utilizes several combo boxes which are required to be filled out by the user. The default value of these combo boxes are "-- Select --". How would I write validation which requires the user to select any other value held in the combo box?

The first step is to define what you mean by "require". What should happen if the user doesn't make a selection?

If the user doesn't make a selection then the form should not allow them to utilize the submit button, which sends the pdf in an email to a specified email address.

Have you searched the forums for validation of required fields? I've posted the code that does that many times...
