Hi Jakobshavn,
Thanks for your reply.
Indeed this would pose a solution but it would also increase the number of columns, which I prefer not to do.
The sheet I'm actually using is way more advanced than the problem I'm describing for now, so I would like to keep it as dummy proof as possible (on the excell side anyway )
So, if there are possibilities, i would like to try the simple function without added columns.
Thanks anyway!

greetings!
