Hi there,
I want to use the =IFERROR(INDEX(COLLECT() function to combine multiple data from different columns into a single column.
So I adjusted this function according to my need:
=IFERROR(INDEX(COLLECT({Dys D1}; {Dys D1}; <>""; {Dys D2}; {Dys D2}; <>""); 1); "")
However, when I put only one range with a criterion, the latter works very well but when adding the 2nd criterion, nothing is displayed.
Is there another method for multiple ranges? Knowing that I have about twenty columns to group.
Thanks in advance,
Cordially
