To carry forward their example, I want to add a third field, City.  The new City field would be dynamic and the values would change based on the State.  

It seems that it should be possible, but I can't quite wrap my head around how to apply the instructions above to this situation.  Any advise, guidance, directions would be most appreciated!

Thanks,

Jordan
