Hi experts
I am creating dashboard with multiple sheet in one sheet i am using sum formula and getting correct result. If i use same formula geting error #MULTIVALUE.

Is any formula to link with cell.

Pls advice.

#MULTIVALUE means that you have asked Webi to put more than one value in a cell. You need to understand what you are trying to put in that cell to fix it. You have not yet given us enough information to help you.
