I'm trying to create a new variable, via change game variable, inside a formula that I can later compare against another variable created inside the same formula, but I need this variable to call a value generated by a different formula rather than assigning it one. I noticed this feature appears to be available under the float options, but I can't get it to work in testing. Always returns 0. Even when I connect directly to the initial node, still 0. The formula itself returns the correct value, I just can't figure out how to call its value by means of a variable. What am I missing here?
