Hey, I want to model a simple shading control (exterior shade). Tutorial from bigladder: Method 2:

Define the Construction of the window without the shade, the so-called “bare” construction.
Reference the bare construction in the FenestrationSurface:Detailed for the window.
Define the WindowMaterial:Shade.
Define another Construction, called the “shaded construction,” that includes the WindowMaterial:Shade.
Define a WindowProperty:ShadingControl for the window in which you (a) reference the shaded construction and (b) specify how the shade is controlled

I have the following obejects within the model:

WindowMaterial:Shade,
    Shade,                   !- Name
    0.2,                     !- Solar Transmittance {dimensionless}
    0.2,                     !- Solar Reflectance {dimensionless}
    0.2,                     !- Visible Transmittance {dimensionless}
    0.2,                     !- Visible Reflectance {dimensionless}
    0.2,                     !- Infrared Hemispherical Emissivity {dimensionless}
    0.2,                     !- Infrared Transmittance {dimensionless}
    0.002,                   !- Thickness {m}
    1,                       !- Conductivity {W/m-K}
    0.05,                    !- Shade to Glass Distance {m}
    0.5,                     !- Top Opening Multiplier
    0.5,                     !- Bottom Opening Multiplier
    0.5,                     !- Left-Side Opening Multiplier
    0.5,                     !- Right-Side Opening Multiplier
    ;                        !- Airflow Permeability {dimensionless}

    shaded construction,     !- Construction with Shading Name

    FixedSlatAngle,          !- Type of Slat Angle Control for Blinds
    ;                        !- Slat Angle Schedule Name

I get the following error message:

   ** Severe  ** CheckAndSetConstructionProperties: The single-layer window construction=SHADED CONSTRUCTION has a gas, complex gap, shade, complex shade, screen or blind material; it should be glass of simple glazing system.
   ** Warning ** WindowProperty:ShadingControl="SHADECONTROL" Both Construction with Shading Name and Shading Device Material Name are specified.
   **   ~~~   ** The Construction with Shading Name="SHADED CONSTRUCTION" will be used.
   **  Fatal  ** GetSurfaceData: Errors discovered, program terminates.

Thank you for your help!
