[VX] How do I draw Variables

[action]

Hello, I am in need of help.
I am creating a Time system for my game using events, and having a problem.
I do not know how to draw Variables, the way you draw health and stuff in a menu.
I am doing this with the Call Script function in VX.
If you could help, that would be great. Credit is a place for you name in the credits in my game.

Thanks!
