missing time calculations

Copper Contributor

hi

 I have a "missing time" issue.  I am inputting start time, finish time, and then missing time. the work sessions are 4hrs and I need to have the missed times from the 4hrs.  I have the calculation to get the missing time but if there has been no start/finish  times inputted then I have the 4hrs left in the column.  from that column I am totalling the missing hours on a summary page, so, if there has been no start/finish inputs I need them to read 0.

Perhaps in C4:

 

=IF(OR(A4:B4=""),0,MAX($B$1-(B4-A4),0))

 

Fill down.
