I am trying to Match 2 prices i have 4 columns.

I have item number for both prices on 4 columns

for example

ITEM # retail price ITEM # wholesale PRICE
123 $20 543 $12
321 $14 123 $18
543 $30 321 $7


Now i need to match the prices by item number so i have to columns: retail
and wholesale with the correct prices. Thanks
