Script help

I put this code on a cube
I did not know what I’d use but I think JavaScript
I entered into OnTriggerEnter (Application.LoadLevel (stasonsquare))
I saw the error Assets / NewBehaviourScript 2.js (3.19): BCE0044: Expecting (, found ‘{’.
ets/NewBehaviourScript 2.js(3,71): UCE0001: ‘;’ expected. Insert a semicolon at the end.
Assets/NewBehaviourScript 2.js(4,1): BCE0044: expecting EOF, found ‘}’.

please help:-|

function OnTriggerEnter() {
Application.LoadLevel("stasonsquare");
                                      }
