GetComponent from class

Hello, Im trying to change a variable of a script from another script but it just won't work.

The sript im trying to acces(A part of it) :

class CharacterMotorJumping {

 var enabled : boolean = true;

 var baseHeight : float = 1.0;

 var extraHeight : float = 4.1;

 var perpAmount : float = 0.0;

 var steepPerpAmount : float = 0.5;
 }

The part where I try to access it :

 var characterMotor : CharacterMotor;
 
 function Start() 
 {
     characterMotor = transform.GetComponent(CharacterMotor);
 }
 
 if(isWeapon==false && canShoot==false)
     {
         characterMotor.baseHeight = 5.0;
     }

It's giving me t$$anonymous$$s error :

BCE0019: 'baseHeight' is not a member of 'CharacterMotor'.

I t$$anonymous$$nk it's because the variable Im trying to access is part of a class. Im new in scripting so please don't hate me if the solution is super simple and obvious. I googled for hours but couldn't find anyt$$anonymous$$ng.

Thank you.
