I have this formula in column AN which counts the occurrences of each value in the long last of values in column AL.
=COUNTIF($AL:$AL,AL3230)
How do I modify that formula so that the count only includes those values where column R's value in the same row is "AM" (without the quotes)?
The result from the formula for the following situation should be 2.
Row R AL
1000 AM 23
1001 PM 23
1002 AM 23
