checkbox array

[eluser]alpar[/eluser]
just got an idea... don't use a callback...use 'required' that comes with the framework...i think it works exactly as you would like it here, and also note, there is an 'isset' error in the language files that gets triggered when the field isn't set (like an unchecked check box), so you could just change the message for isset....

--- Somebody correct me if I'm wrong... I'm kind of busy and don't have the time to test what i am saying, nor run your code sry
