Numbers: Countif with condition the content of a cell
Solution 1:
I managed to find the syntax that works, but I was not allowed to post the answer. It should look like this:
=COUNTIF(Table 1 :: B2:B337;"="&T(A3))
Solution 2:
Seems like you are using wrong argument in condition part of formula - meaning that you should put there string that you are looking for not the address of the cell because Numbers thinks that you are looking for string "C9" and not value from C9.
