worked using excel

so i used the following formula =mod(B3-A3,1) i keep getting the
following error #Name?

=mod() shouldn't cause an error.

My first guess...

If you look at the column headers, do you see A, B, C, ...
or do you see 1, 2, 3, ...

If you see numbers, try changing this:
tools|Options|General Tab|uncheck R1C1 reference style

And reenter the formula.

Or maybe =mod() is called a different name. Do you use an English version of
excel?

If not, maybe this will help:

Maybe I'm missing something but why use Mod? Time is stored as decimal
values.
(3PM - 11AM) will be evaluated by Excel as (0.625 - 0.45833)

Mod returns the remainder of after division.
In this case the "remainder" after dividing by 1 (a day) gives you the same
results as simply doing the subtraction (which will still be a decimal
value)

If you want a "hours worked" result in whole hours, something like:
Int((B3-A3)*24)

Remove 'Junk' from return address.

The reason is that if you use =MOD(end-start,1) you autmatically take next
day into account (if end time spans over midnight) where otherwise you would
need

=B3-A3+(B3<A3)

or you'll get a negative time value and formatting error if you use windows
date settings
