Javascript if statement if (ball.style.left === '0px') {

I think the problem is really simple, but I'm not seeing it. I just want to move the "ball" to the left 132.5px when I click the "dice" and if the ball is 0px left.

I think the if statement is wrong!! Can someone help me?

var ball = document.getElementById('ball');
var dice = document.getElementById('dice');

function move() {
  if (ball.style.left === '0px') {
    ball.style.left = 132.5 + 'px';
  }

}

dice.onclick = move;
