What causes error 'E1072 variable expected' in Unity Pro?



This occurs on function blocks that use input/output parameters. It will be reported if the variable is assigned on the output of an INOUT pin rather than the input pin. It typically occurs on an import of a Concept project on an Analyze of the Unity Pro project.

Move the variable from OUT to IN pin.
