I have a sheet that is supposed to show which people are working where between a start date and an end date.
The FILTER() function is in cell A3.
=IFERROR(SORT( { FILTER({'All Tranches'!C:F, 'All Tranches'!I:J}, 'All Tranches'!I:I>=$B$1, 'All Tranches'!I:I<=$D$1 ); FILTER({'All Tranches'!C:F, 'All Tranches'!K:L}, 'All Tranches'!K:K>=$B$1, 'All Tranches'!K:K<=$D$1 ) } , 5, TRUE ) )The start date is in B1 and the end date is in D1. 'All Tranches' is a sheet that aggregates data from three other sheets. Columns I and K of 'All Tranches' contain dates. If I set the start date to anything before 19/11/20 and set the end date to anything after that, the filter returns the results that I would expect. If I set the start date to 19/11/20, or any date after that, I get no results. I've been messing around with making sure all the source dates are formatted as dates and I've tried using TO_DATE() inside the formula, but it hasn't worked.
A copy of the spreadsheet is here: https://docs.google.com/spreadsheets/d/1pASU-YhvgfLCwM10er4o7fLerOfiPiVk7aFsPkvTHS0/edit#gid=663076104
Why doesn't it work when the start date is 19/11/20 or greater? That date doesn't seem to have any significance in my data.
