Hi
Can anyone help me with a formula

I'm currently working on a work sheet
to calculate working hours / overtime etc.
All is working fine and I have set it so that I can enter start and finish times
and working hours are totalled.

To get the overtime hrs or undertime hrs I have used the
following formula In Cell K8(total overtime/undertime)
=G8-$E$23
which relates to Cell G8(Actual Hours Worked)
and Cell E23( Required Hours which are 07:12)

All works fine and when times are entered, total hours and
overtime/undertime hours are calculated in cell K8.

The only problem I have is that if no times are entered and
the actual hours worked are 00:00 then -07:12 appears in Cell K8
But I would like it to show 00:00 as there is no overtime or undertime.

Is there a formula I can add to Cell K8 to make it show zero if there are no actual hours worked ??

Hope Someone can Help
