Hi All,
From Column A to Column J, these are my monthly sales figures.
From Column L to Column U is the cumulative sales figures.
I would want to write a formula to calculate cell V4 (highlighted in blue), which shows how many months it takes to exceed the target of 28,000 (cell P1).
I have previously done this through a combination of index with the cumulative figure but can't seem to solve it this time.
Many thanks for your help
