Zero as a duration
Hello
I have been struggling to find and answer to this -
I have a schedule that I would like to add a column of durations, the durations are derived from another predefined column using a tick box i.e. when the tick box is checked it shows the employee worked a particular set of hours.
When I tick the box E2 it populates a hidden column D.
E13 adds up hidden column D. But if Jane doesn't work a particular session, the tick box returns a negative value (0) and Numbers strips it of its durational format.
Only when all of the SUM values are returned (all the tick boxes are ticked), then the formatting total works.
Is there a way to force a duration on a "0" value so it is read as 0h 0m? I have tried cell formatting, but it always reverts back to a number.
Note - The blue rows are breaks and not included in the SUM.
Many Thanks
John
