I am trying to amend a current formula I am using to track enrollment. Currently, I have this formula:
=COUNTIF([Date of Injection]1:[Date of Injection]100, ISDATE(@cell)) which counts the amount of cells that have a date so my team can track how many animals we have enrolled in a certain project.
I want to change this to count the number of cells with a date but only if that date is in the past so my sheet summary data accurately reflects current enrollment.
Is this possible?
