This should deal with blanks and errors

=if(isna(VLOOKUP(B2,Books,2,FALSE)),"",VLOOKUP(B2, Books,2,FALSE))

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
