Here's a copy of the formula typed in the cell, word for word. I hit enter and the formula stays in the cell. Do I have to hit ALT, ?? OR something?.

this is all on the same sheet. It doesn't seem to recognize the pivot table cells. It's trying to read the Column and rows instead. I'm sorry you are frustrated, I would have never known to look for the Display setting .
