Running script on multiple objects but script only runs once

I have a GUI list that I want checked off whenever an object is clicked. Right now I can get one object to work but when I want to run it on multiple objects, the script stops working. Thanks in advance

Here's my script:

static var state: int = 0;

var state0tex : Texture2D;
var state1tex :Texture2D;
var objectName : String;

function Start() {
guiTexture.enabled = true;
state = 0;

}

function Update () {
    if (state == 1 && GameObject.Find(objectName) == true){
    guiTexture.texture = state1tex; 
    }
}

That fixed one thing but created another problem. The other script I use to trigger the TextGUI.js script above now has an error:

"An instance of type 'TextGUI' is required to access non static member 'state'."

Sorry this is my first week learning javascript so bear with me. Thanks in advance.

function OnMouseUp () {
    TextGUI.state++;
    Destroy(gameObject);
}

This is what I have added so far.. I don't know if it's of any help

var TextGUI : TextGUI;

function Start() {
    TextGUI = GetComponent.<TextGUI>();
}

function OnMouseUp () {
// not sure what to put here now
    Destroy(gameObject);
}

Don't use static variables. Static = one instance per class/script only.
