Ignore #REF! when adding columns?

[singlgl1]

I have a spreadsheet that updates links from other sheets daily. At th
bottom it tallies the monthly runing totals.Since some of the sourc
sheets do not have data yet entered, I get a #REF! in my cells tha
have no data, therefore my monthly accumalated also has #REF!.
How can I get it to ignore the #REF! and/or show these as blank?
Thanks-Gre

Of course you could edit each of your formulas with an IF statement to
check for error codes and, if exist, return "" (this would be a lot of
work, I'm thinking).

=IF(ISERROR(yourlinkhere),"",yourlinkhere)

However, this works for me and is only one cell to change:

=SUMIF(yourrange,">=0")+SUMIF(yourrange,"<0")

enter cell references to tally in place of 'yourrange'

This should ignore all cells with errors, text and the like.

Good Luck

Where #REF! is returned, you might change your formula to
=IF(ISNUMBER(your formula here),your formula here,"")

This will prevent REF! from returning, and the sum will evaluate
properly.
