School Form: "Expression 'vm.model.iCode | lookup:'islands':'D' | lookup:'districts'' is non-assignable."

[Brian Lewis]

The province and region are derived from the school's island. In conversion to material, these are inputs, but the expression is not valid for an input.

Change to simple quoted text:

{{vm.model.iCode | lookup:'islands':'D' | lookup:'districts}}
