In Excel 2002, I'm trying to color a cell based on this formula:

=pctRange<=1/8

That works fine in most cases. "pctRange" is a named expression and
evaluates correctly to a calculated number. However, sometimes
the the expression's denominator can be zero. In that case,
I'd still like the condition to work.

So I tried this:

=OR(ISERROR(pctRange),pctRange<=1/8)

But the condition still doesn't evaluate as true, even though
the ISERROR(pctRange) expression does evaluate as true.

How can I do what I want? That is, if pctRange <= 1/8 or
pctRange gives a #DIV/0! error, apply the conditional formatting.

Thanks,
Dallman
