lunch break!! well..how to figure

[acetoolguy]

I was a row that looks this..

Arrival Departure Lunch total hours
7:00 am 5:00 pm .5 9.5

I cant seem to get the 1/2 hour lunch to deduct. I have 5 pm - 7am =10 ok

Its a line on an invoice so it also needs to be clear, no military time for
example.
Thanks for any help...

Your problem is that you are mixing decimal hours with times. Had you showed
the formula you are using, it would have been much easier to point you in
the proper direction of a solution. Without it, my guess is you want:
=(a2-a1)*24-a3
Format as general or a number.

Regards,
Fred.

when i tried that all i get is the value in cell A. in my example a 7, where
i want total hours for the day which is 91/2 or 9.5 or even 930 might work. I
can do it by hand if I have too.

Since you have your data laid out horizontally, I think Fred meant to write
his formula this way (he gave you the formula as if your data were laid out
vertically)...

=(B1-A1)*24-C1

I am new at this but I should have caught that too....works perfectly, thanks
to you both.

As you've found out, if you want an exact formula, you need to tell us what
cells your data is in. Without cell addresses, we can only provide a guide,
and most people like me simply start with A1. We assume the user can adjust
the addresses to suit their situation.

Glad you got it working,
Fred.
