Hi there, I'm new here and could do with some help! I'm currently using Excel 2002 (it's all my workplace has!). I have created a worksheet that counts the number of times an item can be used before it needs to be replaced. i have put in a formula that, when a Y is put in one cell, the count is zeroed and continues from there. What I want to do is to make it respond the same way to other letters. If anyone can help it would be much appreciated. I'm no excel expert so layman's terms would be fantastic. Thanks.
