When you create a model using the DoE platorms there is the option to simulate responses prior to the table being made but when you run the model script you have generated the :Y response is included, this means you have to change the model to use the :Y simulated responses you have just generated.
The idea is that if you Simulate Responses during the generation of a model the ':Y Simulated' should be included into the model dialogue, not the ':Y'
