So the element with the id "product" might not exist ?

var productElement = document.getElementById("product");

productElement should now either be the element or null, if it's null
you can't check "value" for it.

so:

<code>
var productElement = document.getElementById("product");
if (productElement != null)
{
   // Code here when the Element Exists.
}
</code>
