Converting 'If else' statement to a 'switch' statement

programming flash

I am attempting to convert the following If statement to a Switch statement and I’m unclear as to the details of the execution of it. If someone could help me with this I would be very grateful. Here is the If statement followed by the shell of my attempted switch statement. TIA.

var spotOne:Boolean = true;
var spotTwo:Boolean = false;
var spotThree:Boolean = false;
var spotFour:Boolean = false;

btn.onRelease = function() {
f (spotOne) {
ball.slideTo(450, 100, 1);
spotOne = false;
spotTwo = true;
} else if (spotTwo) {
ball.slideTo(450, 150, .5);
spotTwo = false;
spotThree = true;
} else if (spotThree) {
ball.slideTo(100, 150, 1);
spotThree = false;
spotFour = true;
} else {
ball.slideTo(100, 100, 1);
spotFour = false;
spotOne = true;
}
};

(attempt at conversion to switch)

var spotOne:Boolean = true;
var spotTwo:Boolean = false;
var spotThree:Boolean = false;
var spotFour:Boolean = false;

btn.onRelease = function() {
var location:Number = ?

switch(location) {
case spotOne:
ball.slideTo(450, 100, 1);
spotOne = false;
spotTwo = true;
break;
case spotTwo:
ball.slideTo(450, 150, .5);
spotTwo = false;
spotThree = true;
break;
case spotThree:
ball.slideTo(100, 150, 1);
spotThree = false;
spotFour = true;
break;
case spotFour:
ball.slideTo(100, 100, 1);
spotFour = false;
spotOne = true;
break;
}
