Decreasing a variable with triggers?

I am using Javascript to make it so that when the player touches the fire in my scene they lose "Armor Points." However, when I step into the Trigger box the number does not change. Again, I am using Javascript and these are they two scripts I am using to try to achieve what I am going for. Any help would be greatly appreciated!

This section is my main cameraScript. It is attached to the Main Camera Controller and is where I declare my static var armor.

static var ammo;

static var enemyhealth;

static var armor;

function Start() {

ammo= 6;

enemyhealth= 9;

}

function OnGUI() {

GUI.skin = customSkin;

GUI.Box(Rect(20,130,130,75),"Armor Points 100");

GUI.Box(Rect(384,50,275,50),"Enemy Health "+ enemyhealth);

GUI.Box(Rect(20,20,185,75),"Health Points 14/14");

GUI.Box(Rect(500,450,190,75),"Ammo Count "+ ammo);

if(enemyhealth>=9){

GUI.DrawTexture(Rect(390,75,25,25), myLogo1);

GUI.DrawTexture(Rect(420,75,25,25), myLogo1);

GUI.DrawTexture(Rect(450,75,25,25), myLogo1);

GUI.DrawTexture(Rect(480,75,25,25), myLogo1);

GUI.DrawTexture(Rect(510,75,25,25), myLogo1);

GUI.DrawTexture(Rect(540,75,25,25), myLogo1);

GUI.DrawTexture(Rect(570,75,25,25), myLogo1);

GUI.DrawTexture(Rect(600,75,25,25), myLogo1);

GUI.DrawTexture(Rect(630,75,25,25), myLogo1); }

if(enemyhealth>=8){ GUI.DrawTexture(Rect(420,75,25,25), myLogo1);

This second script is for the trigger box that currently is not decreasing the number when you step into the trigger box.

static var armor;

function OnTriggerEnter()

{

cameraScript.armor-=1;

}
