What & where are those blueprints? How do those actors get into the game:
- how to see if the number from a variable in a blueprint - what is that actor and where is it?
- the source variable in another blueprint. - what is that actor and where is it?

We don’t know so we can hardly advise without giving you some overall, generic answers.
