Thanks to all for your responses - but I don't seem to have it quite
right. This is my formula:

=IF(=ISERROR(=VLOOKUP(I4,FUEL!$G$2:$I$2044,2,FALSE )),0,=VLOOKUP(I4,FUEL!$G$*2:$I$2044,2,FALSE))



but I'm getting a message that the formula contains an error. I can't
see what's wrong...I must have mismatched parens or something. If
anyone can see what's wrong, I'd appreciate your letting me know. Many
thanks.

=if(iserror(vlookup(...)),0,vlookup(...))
or
=if(iserror(vlookup(...)),"",vlookup(...))

The second formula will work if your summing using =sum(). That function
ignores text. But if you're using something like:
=b1+C1+D1
Then the summing won't work.

I am using VLOOKUP and when that function doesn't find the value in the
table, it returns "#NA" as the value. I then can't sum the column
because of the #NA in some of the cells. Is there a way that I can
return a zero or a null instead of the #NA? I was thinking that perhaps
the VLOOKUP could be combined with IF... Thanks for your help in
advance.
