1.- The lookup table must be sorted by the left most column; therefore I
would try sorting

Not if as per the Ops and your own example, the optional argument of FALSE
or 0 is included at the end of the formula.

Two things come to mind:
1.- The lookup table must be sorted by the left most column; therefore I
would try sorting
2.- If there is a blank space after 63311 or before it, the lookup will
fail, what I usually do is:
=Vlookup(Trim(A3),$A$5:$B$5,2,FALSE)

For simplicity, I have the following vlookup formula listed below, where
the
first number would be in cell A3 and the range I'm trying to find the
number
is in cell A5:B5, and the result is in C5. However, I keep getting an
#N/A
for my response. I have formatted the entire worksheet and all numbers
as a
number and not text. This only happens to several rows in my hugh
spreadheet.
The other formulas work. Any idea why this is happening to these
several
cells?

63311

63311 40813 #N/A =VLOOKUP(A3,$A$5:$B$5,2,FALSE)


Thanks,
