what I did.
A list of product codes from J21:J37 and the product description from
K21:K37 than the price from L21:L37.
In each cell ranging from B21 to B32 I've entered a drop down list
containing the list of product codes. In C21 through C32 I want to display
the product description which is in the cell right next to the code selected
in the B column
