I have a file that is shared by many user. The file contains certain line
items.. Let's say Col A Row 1 has the amount of $100, A2 has $150 and A3 has
$200. Col B1 belongs to user X,C1 belongs to user Y and D1 for user Z. I want
user X,Y and Z to agreed to claim the amount of Col A. They must enter a
secret code. This secret code should identify the user name or intial.

Is there any formula can do this? or anything that I can work around to it?

I appreciate your help to resolve this. Please advise.

Thank you.
