Field formula referencing block attributes

[alxnds5]

Hello,

I'm wondering if someone can help me or has run into the same thing I am. I have a block that carries two attributes (lets call the attribute "A" and attribute "B", I want to third attribute that carries a field formula. This *new* attribute would need to reference the values of the two existing attributes sort of stating, if A=1 & B=5, then show a specific cell from table. I'm not sure if this is something that could be done where we can add a condition before selecting which table cell should appear. Any help would be appreciated.

Thank you!

AFAIK formula fields do not support branching logic.

It can be done with some lisp codes, similar as in this link:
