So I want to access a Forms variable for a field rule, but I am realizing I don't know how. I just want to set a field rule that shows sections based on the value of {/_current_step_id}.

I don't see this variable in the drop down though. If I could get it with javascript then I could put it into a hidden field.

You can't just set it as the Default Value of a field because it will not be the current value of that variable at all times.

So how do you access the form Variables? I really don't see how they are accessible.
