Compare columns, count matches
I'm looking to compare two lists (a1:a10 compared to b1:b10, unnamed). Then,
return the count of original matches between the two lists. For example, if
Joe Schmidt shows once in a1:a10 and twice in b1:b10, then count it only once.
Any advice greatly appreciated? Thank in advance.
P.S. = this will be incorporated into an If statement.
