Pause Menu won't open...

So, i have my script thats a pause menu with some buttons and textures. But it won't open when i hit the "Esc / Escape" key. But it does however open if i click the "MenuActive" variable in the Isnpector. Does anyone know what im doing wrong? #pragma strict

 var menuActive : boolean = false;
 var pauseMenuTexture : Texture;
 
 function Start () {
 
 }
 
 function Update () {
 
 }
 
 function OnGUI () {
     
     if(Input.GetKeyDown(KeyCode.Escape) && menuActive == false) {
     
         menuActive = true;
     
     }
     else if (Input.GetKeyDown(KeyCode.Escape) && menuActive == true) {
     
         menuActive = false;
     
     }
     
     
     if (menuActive == true) {
     
         GUI.DrawTexture(Rect(0, 0, 9000, 9000), pauseMenuTexture);
         GUI.Label(Rect(10, 10, 500, 500), "Pause Menu");
         GUI.Button(Rect(10, 30, 80, 30), "Resume");
         GUI.Button(Rect(10, 50, 80, 30), "Options");
         GUI.Button(Rect(10, 70, 80, 30), "Exit Game");
     
     }
 }
