Cleaner version to pull error if two check boxes are checked

Hello I am working on formwork for double and triple use, and I want it to either pull 0 or error, but I was wondering if there is a cleaner version than the one my good buddy Claudio came up with

([../.././Formwork Assembly/Double Use] && [../.././Formwork Assembly/Triple Use] ? 0 : [../.././Formwork Assembly/Double Use] ? 2 : [../.././Formwork Assembly/Triple Use] ? 3 : 1)
