This should be simple, don't know where I've gone wrong.
I am referencing a date column range on a data log.
Created a new sheet as a summary with date min/max columns.
The formula should be looking for a total count of data entries from the sheet, by month.
=COUNTIF({Delayed Scope Reprocessing Log Range 1}, AND(@cell >= [Date Range (Min)]@row, @cell <= [Date Range (Max)]@row))
