yes, there is a proper way to deal with that error.
whatever this Car Manager is, doesn’t look like it have all the data necessary required to work correctly as you have not populated the variables (right in your screenshot)
All the variables of Carmanager cs is in another scene i just need the one method in my carmanager cs
(Sorry for bad explanation)
Enlighten me please
now looking at your screenshot scene, is called menu, why is the carmanager in this scene?
