Hi

The usual way is to enclose your VLOOKUP in an ISERROR formula.
=IF(ISBLANK(B2),"",IF(ISERROR(VLOOKUP(B2,Books,2,F ALSE)),"",VLOOKUP(B2,Books,2,FALSE))
I haven't tested it, but you get the idea?

Hi I would really appreciate some help with this problem. I have a table
of
data that I am using a lookup on, so that I can preset formulae I am also
using the isblank function to hide the error message when there is no
lookup
value entered. What I'm trying to add to this is something whereby if a
lookup value that isn't in the table is entered, a blank will be
displayed.
What I have so far is this

=IF(ISBLANK(B2),"",VLOOKUP(B2,Books,2,FALSE))

which enters a blank if cell b2 is empty, or the data from the table if
there is a match, what I want is something to catch when there is no match
and enter a blank then.

Any help will be greatly appreciated

Thanks
Steve
