How many replied, regardless of what they said.
You sent five invitations and need the response rate. Put the number of people who replied at all in B7 — what they actually answered does not matter yet.
Solve it on your own to keep the bonus. Each hint gets one step closer to the formula.
The same formula in the other shapes it takes at work.

Every reply in this column is a word, so COUNT returns 0 where COUNTA returns 3. That is the entire distinction between them, and it is the one that bites: point COUNT at a column of text and you get a confident zero rather than an error, which is a far harder mistake to spot.
