how to fix unknown identifier

var Play = false;
var Developer = false;
var Quit = false;

function OnMouseEnter()
{

GetComponent.().material.color = Color.red;

}

function OnMouseExit()
{

GetComponent.().material.color = Color.white;

}
function OnMouseUp()
{

if (Quit)
{

Application.Quit();

}
else if (play)
{

Application.LoadLevel (2);
}
}

PLS FIX IT
“BCE0005:unknown identifier:‘play’”

You have a var called “Play” and you are trying to check “play”. They are case sensitive. Usually, variables are lower case, so rename “var Play” to “var play”.
