Bob - the formula for each day works, but the sum for all hours doesn't.
I
need =SUM(C1.C2) to add the hours worked together. When I enter the sum
formula, it gives me zero.

Use the formula

=--TEXT(B1-A1,"h")

this will SUM normally then

In column A I have the start date & time; in column B I have the end
date
&
time; in column C: =TEXT(B1-A1,"h") to deliver the hours worked on a
given
day. At the bottom of column C, I want to have the total of hours
worked
over
a period of time. I've tried nesting formulars. However, it returns
with a
too many or too few arguments or a #VALUE! error. I'm obviously doing
something wrong. Can anyone show me how it's done?
