Hi Naren, Geromel,
This page - https://forio.com/epicenter/docs/public/model_code/vensim/#vensim-vars indicates a list of Vensim variables that are available.
I find that neither Step nor STEP is present. I’m able to access other gaming variables in my model. This is through the Epicenter api. It was suggested in another post that I use the Flow.js api instead of the Epicenter.js api. Please show some example code as to how I can access a Vensim/gaming variable through Flow.js. By access, I mean to get its value, and not just be alerted if its value changes.
