Why is instantiate and playerprefs not working when combined?

So I need to save a variable, called goodrandomvalue so that I can change the chance for spawn of the ball.

So t$$anonymous$$s works:

     var goodball : GameObject;
     var badball : GameObject;
     var goldball : GameObject;
     var startaudio : GameObject;
     var camera1 :GameObject;
     var spawnwait = 2.5;
     var startingtext : GUIText;
     var goodrandomvalue = .6;
     InvokeRepeating("Spawn", 3, spawnwait);
     function Start () {
     yield WaitForSeconds (1);
     startingtext.text = "2";
     startaudio.audio.Play();
     yield WaitForSeconds (1);
     startingtext.text = "1";
         startaudio.audio.Play();
     yield WaitForSeconds (1);
     startingtext.text = "Begin!";
                 Handheld.Vibrate ();
         startaudio.audio.Play();
     yield WaitForSeconds (.5);
    // Time.timeScale = 0.1;
     startingtext.text = "";
     }
     function Update () {
  //    spawnwait -= Time.deltaTime * .001;
     }
     
     function Spawn() {
            var goodclone : GameObject;
           var badclone : GameObject;
                     var goldclone : GameObject;
     Debug.Log("New Ball!");
            //Add Random Chance for spawn
                    if ( Random.value > goodrandomvalue) {
              goodclone = Instantiate(goodball, transform.position, transform.rotation);
              goodball.animation.Play("11");
              Destroy (goodclone, 8.5);
              }
              else if (Random.value < .55) {
              badclone = Instantiate(badball, transform.position, transform.rotation);
                         //  Destroy (badclone, 24.5);
                           badclone.name = "badclone";
 badclone.transform.tag = "clone";
                           badball.animation.Play("1");  
            }
          
          else if (Random.value > .92) {
          goldclone = Instantiate(goldball, transform.position, transform.rotation);
                                    goldball.animation.Play(); 
                                    goldball.audio.Play();  
                                    camera1.animation.Play("launch");
          }
            
     }

but I need it to save goodrandomvalue, but when I do:

 PlayerPrefs.SetInt("goodrandomvalue", .6);

and if ( Random.value > PlayerPrefs.GetInt("goodrandomvalue")) { Then the goodrandomvalue ball spawns every time. What am I doing wrong? Sorry for the poor explanation, but thanks anyways.
