I have a formula which works to clear the red ! error if the {shift end} cell is blank
IF({Shift End}=“”,“”,MULTIPLY(DAYS({Shift End},{Shift start}),24))
However, I have now amended it to round to one decimal place as some of my cells needed this
ROUND(IF({Shift End}=“”,“”,MULTIPLY(DAYS({Shift End},{Shift Start}),24)),1) and this has caused the red ! error to re-appear in all cells which should be blank. I’m looking for some help to spot what might be wrong with my formula? Thank you
