T used 0 where you used FALSE.
Can you tell me the difference?

Saves a few keystrokes!

0 = FALSE
1 = TRUE

Pete, this worked perfectly. I couldn't get your 2nd suggestion to work
but
your 1st suggestion matched T. Valko's (I'm OK with getting #N/A so I can
manually add those values to one of my workbooks). The only difference
between your suggestiong and T's was T used 0 where you used FALSE. Can
you
tell me the difference?

Thanks so much!

The logic of your formula is "If there is an error looking in book2,
then look in book1". You don't say to look in book 2 if there is no
error, so you might like to amend your formula to:

=IF(ISNA(VLOOKUP(P8,'[workbook2.xls]tabname'!$C:$S,
17,FALSE)),VLOOKUP(P8,'tabname in workbook1'!$A:$F,
5,FALSE),VLOOKUP(P8,'[workbook2.xls]tabname'!$C:$S,17,FALSE))

However, this does not check for the item being in book1 - it assumes
it is there, and if not the formula will return #N/A.

A more generic approach would be:

=IF(ISNA(vlookup_1),IF(ISNA(vlookup_2),"not
present",vlookup_2),vlookup_1)

Looks in table_1 first and returns from there if present, otherwise
looks in table_2 and returns from there if present. If absent from
both, then the error message is returned.

Hope this helps.

I have a new problem I need help with. I am trying to look up a value
found
in workbook #1. I need to lookup the value in workbook #2 and, if it's
not
found there, then lookup the value in a different tab of workbook #1.
Here
is what I have so far.

equalIF(ISNA(VLOOKUP(P8,'[workbook2.xls]tabname'!$C:$S,17,FALSE)),VLOOKUP(P*8,'tabname
in workbook1'!$A:$F,5,FALSE))

The 2nd part of the formula works fine as the lookup returns the
appropriate
P8 value from the tab in workbook 1 when it is not found in workbook2.
However, when the value IS found in workbook2, it returns a value of
FALSE,
not the appropriate lookup value.

Should I be using a different IS function? Any assistance would be
greatly
appreciated!!
