How to use a variable in ProgessBar of Plugin Meta-Bind

How to use a variable in ProgessBar of Plugin Meta-Bind?
I would like to replace 14 and 0 with variables but I just can’t find the syntax. Could you kindly give me an example?

INPUT[progressBar(minValue(0), maxValue(14),stepSize(1)):Progresso]

If there is nothing that could get you up and running in the docs, or if it is too daunting, feed the docs to Claude.ai and maybe something will come out of it.
Otherwise I don’t know the answer by heart. I’d need to look it up too.
