Try reading the selectedId as below. Use getAttribute method

alert("the value of selected IDS="+e.getAttribute('selectedId'));

In Chrome (sorry, I'm using a computer that doesn't have FF, and I'm not going to install it just for this question) it works if you use .getAttribute(). So:

// replace
e.selectedId;
// with
e.getAttribute("selectedId");

Or, in your function:

var id = e.getAttribute("selectedId");
console.log("the value of selected IDS="+id );
if (id != null)
{   
    value += ", "+id;
}

Also, note that JavaScript is case sensitive, so your variable value is not the same as Value, and you were saying Value = where you probably meant value +=. And you may want to use quotes around your element attributes: onclick="createSelected()".
