Can't Vary Electric Thruster Magnitude

[pineapplejordan]

I'm trying to vary the magnitude and direction of an electric thruster, but GMAT crashes with the error:

Coordinate Systems and Central bodies are not supported on the left hand side in line:
Vary 'Vary Burn Mag' SQP1(MAVEN.ElectricThruster1.ThrustMagnitude = 0.5, {Lower = -10, Upper = 10, AdditiveScaleFactor = 0.0, MultiplicativeScaleFactor = 1.0});

There are no coordinate systems or central bodies involved in this line, can anyone offer some advice on where I'm going wrong or what this error means?

Thruster magnitude are very shocked to the electrically manage with the wires to passing some rays of the current from legitimate. That are make retardation on australian writings which can’t to thrust for the magnified.
