Score isn't showing in guiText - unity3d

Question

I have guiTexts called scoreLevel1, scoreLevel2 where i want to show the score from the right levels but it isn't showing any text or scores... There are no build errors. How do I make it show up as expected?
var Score : int;
function Update () {
Score -= 1 * Time.deltaTime;
guiText.text = "Score: "+Score;
TimerOfDeath();
}
HighScores.js:
//run at start if score doesn't exist yet to initialise playerPref
function Start(){
if(!PlayerPrefs.HasKey(Application.loadedLevelName+"HighScore"))
PlayerPrefs.SetFloat(Application.loadedLevelName+"HighScore", 0);
}
//run when level is completed
function OnTriggerEnter(other : Collider){
if(other.tag == "Player"){
Score = gameObject.Find("ScoreCount").GetComponent("ScoringPts").Update("Score");
if(Score > PlayerPrefs.GetFloat(Application.loadedLevelName+"HighScore"))
{
PlayerPrefs.SetFloat(Application.loadedLevelName+"HighScore", Score);
}
}
}
GetHighScores.js:
#pragma strict
function Start () {
var hscount = 1;
var iterations = 1;
var maxIterations = 5;
var findtext = gameObject.Find("scoreLevel"+(hscount));
while(hscount < 5 && iterations < maxIterations){
if(!PlayerPrefs.HasKey("Level"+(hscount)+"HighScore")){
findtext.guiText.text = "Level"+(hscount)+ ": " + PlayerPrefs.GetFloat("Level"+(hscount)+"HighScore");
hscount++;
}
iterations++;
}
}
