title: How can I display a DoubleProperty on my scene?
body: <p>I want this totalSalesAmountProperty to display the value but even after it is updated, and has an actual value, it still doesn't display. I know this has a value because I system.out the getter method and I get a value. Why would that be happening?</p>
  
  <pre><code>Label lblTotalSales = new Label(String.valueOf(newSale.getTotalSalesAmount1()));
  </code></pre>
