Hello, I am trying to use INDEX & COLLECT instead of VLOOKUP as I want to return a value from another sheet based on two criteria.
I want to lookup a column containing Building ID and find it in the source sheet, returning who has completed the check. I also want to check the date completed was within a date range of -1 & +3 days of the due date, for which I have added a 'helper column' to show if the check was completed on time. The helper column is in the same sheet as the formula.
The formula I have tried is:
=INDEX(COLLECT({Completed By}, [Call Point Building &ID]@row, {Helper}, [Completed On Time]@row, =1))
The response I am getting is #UNPARSEABLE
Please can someone let me know where I am going wrong?
