Currency score increase on pickup

Hello, i was wondering if there was a way to have a pickup effect an textgui so that it adds to it on each pickup. My currency script looks like this atm.

//Rotate Script

function Update() {
    transform.Rotate(0, 2, 0);
}

//Sound & Destory

var CSound : AudioClip;

function OnTriggerEnter () {

     AudioSource.PlayClipAtPoint(CSound, transform.position);
      Destroy(gameObject);

}

Sorry if it seems like a dumb question but im quite new to unity. Thank you in advance for any answers.

on your currency script add some lines under the ontriggerenter bit that says something like.

var player : GameObject;
var CurrencyAmount : int = 1;

if ((collision.gameObject.CompareTag ("Player"))
tempvar = player.GetComponent(ScriptThatHandlesMoney)
tempvar.Money = tempvar.Money + CurrencyAmount

this assumes your player is tagged Player. set the player in the player variable, basically this finds a script (bit in brackets) which is a component of the player then adds the currency amount variable to the player scripts Money variable

In response to your comment its not supposed to work its example code of the syntax you wud use and in what order. To print variables to GUI use something like

GUI.Label (Rect (10, 10, 100, 20), "Money" + moneyVariable);
