Hi I am trying to simulation a window which has dynamic Solar Transmittance. I prepared the following code for that. It does not work. Could you please help me fixing that?

EnergyManagementSystem:Sensor,
 T1,
 Environment,
 Site Direct Solar Radiation Rate per Area;
Area;  
EnergyManagementSystem:Actuator,
 T,
 b_0_Srf_2_glz_0,
 WindowMaterial:Glazing,
 Solar Transmittance at Normal Incidence;
Incidence;  
EnergyManagementSystem:Program,
 D,
 SET Site Direct Solar Radiation Rate per Area = T1,
 if site Direct Solar Radiation Rate per Area >= 300,
 Solar Transmittance at Normal Incidence = 0.2,
 ELSEIF site Direct Solar Radiation Rate per Area < 300,
 Solar Transmittance at Normal Incidence = 0.5,
  ENDIF;

EnergyManagementSystem:OutputVariable,
  M,
  M-b-0,
  Averaged,
  SystemTimestep;

ThanksEnergyManagementSystem:OutputVariable, M, M-b-0, Averaged, SystemTimestep;
