I need help with an error

My javascript is:

function OnMouseEnter()

{

renderer.material.color = Color.blue;

}

function OnMouseExit

{

renderer.material.color = Color.white

}

function.OnMouseUp { Application.LoadLevel(1) }

Every time I start up my game it says "Assets/NewBehaviourScript 2.js(17,1): BCE0044: expecting EOF, found 'function'."

What should I do?

you're missing () after OnMouseExit and OnMouseUp, you have a . before OnMouseUp, and you're missing the semicolons after Application.LoadLevel(1) and Color.white
