Proc Logistics

I normally run statistics through a GUI in Enterprise Guide (EG). It uses various macros. For whatever reason its ordered logistic regression never runs. I get errors like the following:

ERROR: There are no valid observations.

When I run the following for the same data (it is in the work file noted) it runs. But I was not sure if I was using the right code below for ordered logistic regression.
