Calculating an average with conditions.
This is returning #DIV/0!
Is this because the "No. of calls" column is also subject to a formula?

I have two columns of data, one of which I need to calculate an average of
but only if the data in the 2nd column is of a certain value.
I can't work out how to do this...
For instance, I need to calculate the average number of calls taken within
week 37.
My columns look similar to:
No. of calls Week no.
10 37
8 38
4 37 etc
