SetActive(false) not working

for some reason, t$$anonymous$$s script doesn't work, I have it set to disabled at start and when the value appears it enables and there is a button to disable it, but the button just doesn't do anyt$$anonymous$$ng. I have it all set up but the button just doesn't do anyt$$anonymous$$ng.

here's my code:

     public Slider sl;
     public GameObject w;
     
     void Update()
     {
         if (sl.value >= 194) { w.SetActive(true); }
     }
     
     public void close()
     {
         w.SetActive(false);
     }
