Hi @Michael Casey, That is not a temporary fix. Neither does it apply only to Fusebox. It is the result of a fundamental change of behaviour of the ColdFusion server, effective from ColdFusion 2021 Update 13 / ColdFusion 2023 Update 7 onwards. Starting with those updates, ColdFusion defaults to

searchimplicitscopes=FALSE

. If you fail to prefix a variable name with an appropriate scope identifier, you will get an error.
