Thread:Project:Support desk/Using ParserFunctions with External Data

I am trying to use the  ParserFunction inside a   call but it does not work. Example below.

It seems that only the first value goes trough the ParserFunction  and it determines the result. When the first is not empty yes is displayed. When there is a empty on the second row yes is displayed again where it "should" display no. The ParserFuction is working but not for all rows. I think I am doing something that is just not possible but is there a way to get this to work? Thanks.
