From within a UDT Tag definition (Value Changed) script This line of scripting code (below) worked perfectly for many days `ga = Maintenance.GageAttention(Gage)` Suddenly, today it started erroring out with (error below) `global name 'Maintenance' is not defined` Does anyone know what could have caused this? ---

Did someone change the ‘Gateway Scripting Project’ setting? [https://docs.inductiveautomation.com/display/DOC81/Project+Library#ProjectLibrary-GatewayScriptingProject](https://docs.inductiveautomation.com/display/DOC81/Project+Library#ProjectLibrary-GatewayScriptingProject) ---
