non-static Variable in script on multiple gameObjects reset. Why?

I have a script that controls multiple buttons. The buttons are for selecting skins in a 2d game. I have a variable called SkinStatus, which shows if the specific skin is bought, not bought, or equipped. Right after running Load(), which loads in all of the statuses for all of the skins from JSON, the program sets the SkinStatus variable, but it just becomes 0 after the function and functions called from it finish. Since the script is on multiple objects, I need each one to have its own SkinStatus value. Thanks for any help! Please ask questions if you have any!
