How do i call a variable from another script?

So, in a game i’m working on i have a money system and it is in a script attached to a camera, i also have a onTrigger event that takes money away. But i don’t know how to call the money variable to the trigger script. i’m new at this and i need a more spoon-fed explanation.

Thanks, Willosoft Dev. Team

I explain it very clearly in these two topics.
