How to set GUI button "1" to "0"?

Hi I'm trying to set a GUI button to triggerGo = 0; Because I'm using a Static Variable to enable a script in other object.

So a need to use the same button, But when I hit the button its only makes "triggerGo == 1" so I can't disable the script in my other object.

Here you can see my script

Any advice?

Thanks in advance!

 function OnGUI (){
 
 GUI.skin = Skin_power;
 if (GUI.Button(Rect(870,227,80,56),"")){
      audio.PlayOneShot(beep);
     triggerGo = 1;
     print(triggerGo);
     }
