COUNTA (total) divided by another cell (google sheets)

Hi guys

Here's my spreadsheet

https://docs.google.com/spreadsheets...it?usp=sharing

On the October tab, in cell B34, i am trying to divide a COUNTA (number of individuals by a price in B37 to know how much each individual has to pay to play football I am booking).

see what I am trying =COUNTA(C2:C32)/B37

it isn't working. Can someone please advise?

You need to divide B37 by the count, not the other way round.
