Hey, how can I do this:

If one picklist field has value (any other than "none"), the other picklist field may not be selected (must be "none")?

Do  anyone have a solution for this? I've tried to reach to solution by using AND and OR statements (with ISPICKVAL), but I have been more or less validating the field to be required if the other field has been selected. So right now I'm doing it in the wrong way.

Regards,
