Scripting help

[Black_knights55]

Hey,
I was scripting with the graal system like 6-7 years ago so I lost a lot of my knowledge about it lol. My question is simple, I just want to know how I can add a variable to a player like a experience count or a level or anything like that so the variable is ON the player.

I know it's a really noob question but I just can't remember how I did that.

Thanks,
Rick
