I have a worksheet with 1000+ line and I need to write an if function to
look
in one particular column to tell me if certain number are among the
various
numbers listed in that column. Example:

Column contains account values from 100000 to 900000. In a new column, I
want to write an IF function to say YES if the number is 1 of 3 numbers
(200000, 300000 or 400000), otherwise NO.

I appreciate any assistance.

THANK YOU!
