Ok - getting rid of the error is probably a better approach.

The errors come from an extracted list of customer names using the
array formula you provided before Frank:

{=INDEX(Custnames,SMALL(IF(RngA="Include",ROW(RngA )-3),ROW(1:1)))}

I extended the formula down further than was neccessary to acomodate
when the customer list growths. So that's were the #NUM! errors come
into play. I guess I don't neccessarily need to do this - but I want
to automate my xls as much as possible for when others use it.

If there is a solution it would be helpful, - but I guess not the 'end
of the world' :-)

I'd be happy to send you the spreadsheet if need be.

Elijah
ps. Biff I'll try your formula - when I remove the errors from the
list. thanks

Hi
post your used formulas for the range names
One importan thing: Don't use ranges such as A:A. Use A1:A65000 instead
(if you really need such huge ranges).

If your ranges itself contain a #NUM error post the formulas which
create these errors. You may change them to
=IF(ISERROR(your_formula)),"",your_formula)

Hi again,

I posted a similar question a week or so back - but now I'm having
trouble with using the SUMPRODUCT or SUM(IF( type function,
especially
when the ranges I'm referring to in these functions have #NUM!
references.

btw - thanks Frank, Aladin for your previous advice on a similar
question.

Using the SUMIF function somehow aviods this problem, but not when
summing using multiple criterias (ie. SUMPRODUCT or SUM(IF( array
type.

Can anyone help me in avioding the #NUM!? Is it possible?

Here is an example of the functions:

=SUMPRODUCT((RangeName1="Customer")*(RangeName2=10 00)*TheSumRange)
This returns #NUM! - I guess because all of my ranges include #NUM!.

The other array type:
=SUM(IF(RangeName1="Customer")*(RangeName2=1000),T heSumRange)
This also returns #NUM!. I tried wrapping this with an ISERROR but
couldn't get it to work - eg.


=SUM(IF(ISERROR(RangeName1="Customer")*(RangeName2 =1000),TheSumRange),,
(RangeName1="Customer")*(RangeName2=1000),TheSumRa nge))

Assuming I want to leave the error terms within the list - can this
be
done?

Again your help appreciated.

Elijah
