Forest plot in SAS - sas

Question

I have downloaded this code from the web and I need to create a forest plot for each of the variables that have values as 'YES' and 'NO'. It works when each variable have different values however my data has same values for each of the variables. I tried several options but it is not working. Original code is downloaded from http://onsasprogramming.blogspot.com/2016/01/forest-plot-of-hazard-ratios-by-patient.html.

The forest plot should give YES and NO under HTN and Obesity but it doesn't. Any tip would be appreciated.
