 I have no idea what that extra stuff means but it worked perfectly. Do you have any recommendations on some kind of guide or how to basics on writing these kinds of formulas?   Thank you! 

 I opened what you have, and I have exactly the same formula (except the field obviously). The difference is I'm using a multiple selection list box instead of a repeating table that you enter info into. Do you think this makes a difference? Also my list is coming from a SharePoint List. I am still getting the comma in front of the first ...

 That removed the comma at the end, but not the one at the beginning. I'm really new to writing these formulas, I keep messing with it I just can't seem to get it.   Much appreciated!!
