Below is what I am using:
=(COUNTIF(CABLE:CABLE, 1)) / COUNTIFS([TURN OVER]:[TURN OVER], "ECORE") this formula works and returns a % in my sheet summary that looks correct.
When trying to get results from a different "turn over" I get incorrect results
=(COUNTIF(CABLE:CABLE, 1)) / COUNTIFS([TURN OVER]:[TURN OVER], "AB")
I am using checkboxes to collect information in the cable column, but with no boxes checked for cable that are in turnover "AB" I get 28% as result in sheet summary.
