Summing a number only once

[cmatera]

I have a 14 day pay period where I am trying to calculate the balance
of time at which a person is "off pay"

After 14 days I want to show the total amount of time a person is off
pay. So for example -

From 8/23 - 9/5/08
I have a person who is off pay for 8 hours (-8) the first week and
then another 6 hours (-6 hours) the second week. I want to total up
the amount of time this person is off pay (-14)

The problem I'm running into is as follows:
Each day has a balance cell. So if a person is off pay 8 hours the
balance cell is populated with that -8 However I only want to
calculate this once

I'd be glad to clarify some more if people need...any help is greatly
appreciated.

Thanks

Hi,

It would help if you showed us a sample of what the data looks like and what
you want displayed where.

The general approach might be =SUMIF(Range,"<0")

=SUMIF(A1:A14,"<0")
