Add a select field to the profile

Hey there

I'm still trying to learn all of this and damn this is cool ****. Anyway, I installed the gender hack and was going to use it to install another profile select box. Then I saw the very cool CP tool for adding a field to the profile. It currently only allows you to add a input box. I decieded to modify it so I could add my select box from there. It wasn't very hard and the hack is pretty short.


Here it is in a nutshell
I added a textarea field to the add/edit profile field
if you want the new field to be a dropdown, you enter the dropdown values. each line represents a new option tag.

Ex. you want a new field called "sex" that is a drop down with
the choices male,female, and other.

Make the new field as usual.
Set Field Length. (1 would be a standard dropdown)
Set Maximum Input (I'd leave it at 250)
In the Select Box Items text area type

Male
Female
Other

each on it's own line.

This is a great hack, I've had it installed on my board since the beginning. I'm hoping to tweak it, though. I have drop-down boxes for required fields, and the default is the first field in the list. If a user doesn't actively select a different option from each drop-down, the default is what ends up as part of their profile. I'd like to avoid this issue, forcing new registrants to actually select an option. I would imagine this would involve adding an extra field for each drop down that says "Make a selection" - that part is easy.

What I'm wondering how to do is, how do I get the system to return an error if they do not make a selection?
