Hello Im creating a driver and with basic funtion that fails, i just write this Qaction with one parameter and one button to test

string protocolString = (string)protocol.GetParameter(Parameter.protocol_1001);
protocol.Log("-------------" + protocolString);

but in the log i have this error:

Compilation failed for QAction 1002

(21,67): error CS0103: The name 'Parameter' does not exist in the current context

2025/06/05 13:58:27.353|SLManagedScripting.exe|ManagedInterop|ERR|-1|478|No CodeBuilder found (element 12504/13336 trigger 1002 cookie 0)

	Input: new = <NULL>

If i use the number of the parameters and no the "paramerter" class i have no error, im using the Dis version 3.1.10

Any idea of the problem? before i work without problems

Thanks
