RE: problem adding

Tech-Archive recommends: Fix windows errors by optimizing your registry

You are wrong, it is your formula in G that creates this error, if the time
fields are empty your formula returns 1 which is the same as 24 hours, change
the formula in G to (I am using your example in G10)

=MOD(E10-F10,1)

or if I misunderstood you

=MOD(End_time-Start_time)

that is regardless if the end time technically is less than the start time,
another way which maybe makes more sense


=E10-F10+(E10<F10)

having said that I find it odd that you use E as end time and F as start time
I would say 99% of excel users would put IN in E and END in F

regardless, if I misunderstood just reverse the cells but these formulas
will work
