How to switch from FenestrationSurface:Detailed to using WindowMaterial:SimpleGlazingSystem

I have done EnergyPlus simulations using FenestrationSurface:Detailed, using glazing and frame data from LBNL WINDOW (bsdf files). I want to do a regression analysis by targeting U-factor and SHGC. So, I want to use the simple glazing system to enter the U and SHGC data.

I have tried to reference the exterior window construction in the detail surface (see code samples below). But this doesn't work. Can someone be of assistance with this? What am I missing here?
