I need to create a match-up formula that returns the value from another
column. I have 2 columns (trailer numbers and their corresponding
commodity), and I have another column which has the same trailer numbers and
I want to create a match-up program that will search in column D for a match
in column A, then return its value in column B; here is an example:

Column A Column B Column D Column E
Trailer Commodity Trailer (match trailer# in col. D w/ col. A
5271 Clamp 5271 return value in col. B)
5502 Clamp 7912
7912 Clamp 8659
8592 Clamp 8682
8659 Clamp 8900
8682 Cart 9233
8900 Clamp 10837
9233 Clamp
10837 Clamp
10908 Clamp

i tried VLOOKUP but it only works for trailer #'s that start with a letter,
not the trailer #'s with a number (it returns #N/A in this case).

Thanks for your help.
