I need to figure out a formula for the following senario:

I have three columns; Column "A" has is a list of "license" numbers; Column
B Would be a name associated with that number; and Column C is a the result
of a question regarding Column A.

I have a list of 49 plus and growing license numbers associated with
individuals. Data is coming in on a daily basis. The formula that I need to
create would be something like this: If A1 = 18, then put Jim Jones in
Column B, but if Colume A1 = 2350, then put Josh Smith in Column B
Like I mentioned there is a listing of 49 plus and growing license numbers
associated/assigned to an individual...

How do I figure out the formula for this and have it change automatically so
that I I dont' have to type the names individually every time new data comes
in... the data is coming in by way of a questionnaire on a website, which is
then brought into WORD, then sorted and stuff that is left blank is deleted
from the table.

thanks....
