Getcomponent Javascript error

Hello so im new to java script, and get this error
No appropriate version of ‘UnityEngine.Component.GetComponent’ for the argument list ‘(function(): void)’ was found.

im trying to get the “money” var from the the Main script to use in my Store script.

Here is my codes:

First one:(called Main)

#pragma strict
var clicks : GameObject;
var totalclicks : GUIText;
var moneytext : GUIText;
var clicked : boolean = false;
var click : int = 0;
public static var money : int = 0;
function Start () {
click = 0;
money = 0;

}

function Update () {
totalclicks.text = "Total Weeds: " + click;
moneytext.text = "Weed Money: " + money;

}

function OnMouseDown()
{
click += 1;
money += 1;
}

------------------------
Second one(called Store):
#pragma strict
var factoryt : GUIText;
var factory : int = 0;

private var mainScript : Main;

function Awake (){
mainScript = GetComponent(Main);

}

function Start () {
factory = 0;
}

function Update () {
factoryt.text = "Factory: " + factory;
}

function OnMouseDown(){
if(mainScript.money >= 100){
factory += 1;
mainScript.money -= 100;
}

}

Ensure that the Store script is on the same object as the Main script otherwise it will not find it. GetComponent is not a global find X anywhere. That said, ensure you use the right GetComponent function/method.

function Awake (){
	mainScript = GetComponent.<Main>(); // use the generic version to get it in java/unityscript
}

“Main” is a reserved keyword in many programming languages. Call your script something else ("MainScript " would be fine) and also change the GetComponent call to match.

Try changing you class “Main” name to something else.
