Sumproduct() usage
The bigger the range and the more formulas you have, the slower recalc will be.
Lots of times, a bunch of =sumproduct()'s could be replaced with a single
pivottable.
And look at:
tools|Options|Calculation tab
(xl2003 menu system)
If you're using manual calculation, you may want to turn off the: "Recalculate
before save" option.

Now that I understand the Subject formula I use it extensively and in

to
be having is that after I create 3 or 4 sheets where there are maybe 2,000
or 4,000
rows using the Sumproduct() many "things" begin to happen. Recalc time
being the first, resorting to Manual Re-calc mode; But now I seem to be
having problems doing the normal File Save function. Has anyone experienced
this situation?
Are there no-no's involved in what I've done? More important is there a
remedy,
apart from a total abandonment of the functions usage?
Thanks in Advance,
