Validation on multi select picklist

Hello gurus,

I am trying to create a validation on a multi select picklist and was hoping to get some help. Here is the scenario:

I have a multi select picklist that will have three options. User can select one or all three. Depending on what the user select some fields will become required. I know how to do this in a regular pick list but not sure how to do it in a multi select picklist.

I would appreciate any help with this.

Thanks,
KalluMama
