GMod Lua- How to use 'self' outside a function (in a STool)?

[MysteryPancake]

Okay, so I'm trying to make a fairly basic STool, except when I try to use the variable 'self' to sample a ClientNumber (and make it a bool) to determine an 'if' sequence, a very painful error keeps popping up (self is a nil value).

How can I use the var 'self' WITHOUT using a function containing TOOL at the start? This is the annoyance, just add it into any STool script (outside a function) and the error will pop up.

local ANYTHING = tobool( self:GetClientNumber( "SOMETHING_WITH_A_NUMBER" ) )

(Replace the value 'SOMETHING_WITH_A_NUMBER' with an actual command if you want)

It's meant to set a var 'ANYTHING', checking whether the ClientNumber of 'SOMETHING_WITH_A_NUMBER' is true or false, but it cannot check the variable 'self' because it is undefined.

How can I define it?
