Hey Weston Kaunk,
sorry for the long delay. Ehm, the variable is actually useless (old system) and you can delete it right away. I stopped the series but added a few more things in the current project to implement things I couldnt do in the video series format.
Is it still not working for you? They best way is to go to my discord server where I am very frequent (not so much on itch.io). State there that you baught the project and you need some assistance.
I will upload a newer version of the engine right now and hopefully all the issues are thing of the past.
