Thanks, I'm waiting patiently.

I have another question you might know the answer to. How do I exclude hidden rows in a formula I use? I have filtered one of my columns on the text that is displayed, and now I want to see if there has been a 'switch' by comparing a cell with the previous cell. IF(AB2=AB5; same; switch) But when I do that, the formula automatically includes hidden rows and transforms the formule into comparing a cell with 3 cells before.
