It shouldn't have a problem.

I copied and pasted it into the next 3 cells in the column and the 3rd cell
(4th counting the original) had this formula:

=SUM(IF(ISNUMBER(C675:C681-D674:D680),C675:C681-D674:D680))+IF(ISNUMBER(D681-C681),D681-C681)
and it was showing as array entered, so it calculated correctly - or least
as expected.

If that is what you are talking about.

It works but as you can tell I have to paste it into nearly a hundred
cells
and when I try it doesn't do that auto formula format that excel does. Is
there a way I can make it copy/paste friendly or do I have to edit all the
cells directly?

Thanks So Much,
Rob

Entered with Ctrl+Shift+Enter rather than just enter (since this is an
array
formula)

should work.

I have this formula that subtracts one cell from another and then adds
that
to a running total.

=(C672-D671)+(C673-D672)+(C674-D673)+(C675-D674)+(C676-D675)+(C677-D676)+(C678-D677)+(D678-C678)


My problem is this; on occasion there will be the need to have some
cell
pairs blank or they'll contain "N/A" in them. When this happens I get a
Value
error. How can I correct this?


Thanks in Advance,
Rob
