Hi

I want to know if i can combine the following two formulas into one. I have
two spreadsheets in the same work book. I want column B of spreadsheet 2 to
compare with column B of spreadsheet 1 to see if the code exists. If the
code exists i want comment located in column E of spreadsheet 1 to show in
column E of spreadsheet 2. Make sense?

=VLOOKUP(B1,'9-6-09'!B:B,1,FALSE)

=IF(E1='9-6-09'!B1,'9-6-09'!E1,"null")

Thanks
