Hi, I have a sumproduct formula which is returning an #N/A error, and wondered if someone can work out why.
I have attached the workbook and the desired result - but basically I would like to populate E6:E10 with values from the Engage tab.
The result in E6 should be - 3741 and E7 should be - 2834
Is it because i am referencing a linked cell A1?
Any suggestions? many thanks
