First you would create a table (that you probably already have) containing
the product number and the product description. Then in the second cell
(where you want the product description to appear, use a VLOOKUP formula.
Look it up in Help. HTH Otto
You need a 2 column table of numbers and descriptions
use the vlookup function to get the description
I.e. something like =VLOOKUP(B1,$C$1:$D$11,2,false)
where
B1 is your cell with the number
C112 is the range with the table
2
is the column to look in
false indicates you need an exact match
the numbers in C column should have been sorted ascending
