Hello Macropod, thank you very much for asking. There are no true 0 values. Each of the four fields either have values coming from Excel or they don't, and none of the four fields will have a 0 value. I would really appreciate if you know how to do this.

If you have the solution and if it's not too much trouble, I would really appreciate both solutions. At some point in the future, I may need to allow the 0. Thank you.
