How to make the system usable only by whitelisted players?

Hi guys, I’m trying to make this Spear Skill system so that only I and whitelisted people can use it. Does anyone know how, or what I should change?

all of it. pull it apart and try to put it back together starting from nothing and just use it as a reference.

I would like to try this, but I’m not advanced enough yet to make it fully functional without running into bugs.

maybe try something a bit easier like +1jump/sec

from start to finish
