Hi:
Yes, there is an issue with that program, thanks for pointing it out. We are reviewing it.
If your %LET statement in SETUP.SAS includes the data subfolder (which is correct for SAS OnDemand), then you needed to take the /data out of the datafile= part of the code.

S:\workshop is the classroom path for the file and in that environment, we use a slightly different path for classroom students. However, for SAS OnDemand for Academics, you should make sure that your %LET statement includes the /data subfolder and that your model syntax does not have a second reference to /data.
Thanks for bringing this typo to our attention.
Cynthia
