calc: test a text cell for any occurrence of a specified letter

I have a Calc spreadsheet in which the cells in one column contain up to four letters (or none at all). I need to be able to test each cell in the column to see whether it contains the letter C.

I built the formula below, but it returns only “Err:510”

IFS(MID(N133,1,1),=“C”,MID(N133,2,1),=“C”,MID(N133,3,1),=“C”,MID(N133,4,1),=“C”)

There ought to be a way to accomplish this but apparently I’m too thick to see it. Any help greatly appreciated!

IFS tests that all conditions are true simultaneously, not that any of them is satisfied. Another way would be using OR:

=OR(MID(N133;1;1)="C";MID(N133;2;1)="C";MID(N133;3;1)="C";MID(N133;4;1)="C")

Thanks, Mike!

I knew there was a way to do it, but for some reason (my stupidity, I suppose) I was so concentrated on making IFS work that I clean forgot about OR (slaps self in forehead).

=ISNUMBER(FIND("C";N133))
