Simple on off script in 2019,How to Simple On/Off to turn off script 2019?

Ok so I have a script, a skill the player activates on key strike and then deactivates on the same key strike.

Ive put the script to be deactivated and reactivated on an object in the hierarchy as per one of the untold many tutorials i have read or watched. i have then attached the Below script to the player ( script attempt number 10ish)

timeObject is object SlowTime is script

public class SlowOnOff : MonoBehaviour { public GameObject timeObject; SlowTime slowTime;

 private void Start()
 {
     slowTime = timeObject.GetComponent<SlowTime>();
 }

 void Update()
 {
     if (Input.GetKey(KeyCode.T))
     {
         timeObject.SetActive(false);
         slowTime.enabled = false;
     }
     else
     {
         timeObject.SetActive(true);
         slowTime.enabled = true;
     }
 }

}

I am probably so far off its not funny...soooo where do I start

Thanks
