hi Angie
one way:
- first create a helper column (lets say a new column A - therefore
your other columns are shifted to the left) and put the following
formula in A1 (this concatenates item code and year):
=C1 & D1 and copy down
In F1 put the following formula
=IF(E1=2004,IF(VLOOKUP(C1&"2003",$A$1:$E$999,4,0)< D1,"price
change","no change"),"")
copy down
where column B=category, column C=item code, column D=price, column
E=year
You can hide the helper column A if you like

problem statement:

i am working with a pricelist.
i have 4 columns. column A=category, column B=item code, column
C=price, column D=year.
i want column E to contain a formula that will appear the value false
if the price between year 2003 and year 2004 has changed, and the
value true if it has not changed (formula ignores 2002 price). p.s.
item code is not unique for each year as it may appear several times
in a year if it belongs to multiple categories.

how could create this formula?

pls help me!!!
