For the above example, I would like a formula that can count how many times
"a" appears in column 1 with "4" in column 2 of the same row. *The output for
this example should be 2

In column C: =A1&B1, copy down. Then in any cell, assuming 5 rows:
=COUNTIF(C1:C5,"=a4") - but there's probably a more elegant way!
