I am also trying to count cells where Column B is not null AND the
adjacent value in Column A is 1.

In the following example, I would like a count of 2.
A B
1 3214
2 23190
1
1 9876
2 6789

I tried using COUNTIFS(A:A,1,B:B,ISNUMBER(B:B)), but that returns
zero.

I want to perform a sum of squares with conditions. *I know there is a
SUMSQ function and a SUMIF function, but is there a SUMSQIF function?

I have a table like:
ColA * *ColB
1 * * 3435
2 * * 45345
2 * * 230
1 * * 9685

I want to sum the squares of ColB, if ColA=1
