It is quite possible. Take a look at the following look for some guidance on

Hi.

I have 2 lists like this:

Code Name
X12 David
Z55 Arnold
AB223 Meechie etc

I would like to do cell validation and give user the option of using drop
down list in either of the columns, while the other column gets populated
by
using VLOOKUP.

Is this possible, or an insane request?! Pls do help
