Hi Patty,
Is there anything wrong with the custom cell formatting.
Format, cells, number
choose one that has red, though I think it RED may have been left out
of some language versions, so you could always take the formatting that
matches what you want and use [RED] in the second part. semi-colon
is the US list separator.
Positive Numbers(default); Negative Numbers(default); Zero(All other numbers); Text
#,##0.00_);[Red](#,##0.00)

If you really want to use Conditional Formatting, I have a page
http://www.mvps.org/dmcritchie/excel/condfmt.htm
but it would certainly not be as efficient as custom cell formatting.
And Conditional Formatting is lot harder to keep track of what
you've done.
