How to use a wildcard

In the example below I have used the COUNTIFS function to count the number of members who fulfill the two criteria in the report, and the SUMIFS function to calculate the total amount paid if both criteria are met.

=COUNTIFS(B2:B11,G2,D2:D11,G3)
=SUMIFS(C2:C11,B2:B11,G2,D2:D11,G3)
