thank you. Yes, i added in a separator and it works now....
concat("FilterOwssvr /dsname=SDOwssvr /filter=Study_x0020_Director_x0020_Name /value=", .) this gave me an error because the values did have a comma.
i changed to:
concat("FilterOwssvr /dsname=SDOwssvr /filter=Study_x0020_Director_x0020_Name /value=", ., " /delimiter=~") this worked!
QRules Rocks!!!
