validation rule for people picker

[AugustoGG]

I need to set up a validation rule in a people picker of a form that if the user wants to enter a group lets call it "group A" and enter a group called "group B" he can not enter both of them. So if he enters "group B" he can not enter "group A" and if he enters "group A" he can not enter "group B".

I already solve it, I use inArray(namePP, stringttofind).
