I used INDIRECT to get a list for Data Validation, but the result is totally different in these 2 scenarios.
Scenario 1: use offset to get a dinamic range, the result is error.
Scenario 2: get a range without OFFSET, the result is normal.
offset formula needs a height and a width. In your formula you have no value for height which should have been COUNTA formula and 1 in your width area like below:
if you do not enter any value in both height and width or enter 0 in these fields, offset formula would return #REF error.
@erol sinan zorlu
thank you so much for your time.
I revised the OFFSET formula and it referred to the right cells.
