Hello, here's my issue : I keep having an error telling me that the types are incompatible even though my "R.id.total\_akylux" is a Number(Decimal) in the XML file, and the result is given in decimal. I don't really understand why do i keep having this error. If someone could help me, it'd be really useful. Thank you
