Class Array In Custom Object Not Working?

I have created a class array (or variable that contains an array) and am trying to add an element to the array when a new Element object is created. Thus, the line of code to add a new element to the array is within the Element object's constructor function. However, the browser just gives me an error "object expected on line 9", the line of code trying to add an element to the array.

Are arrays not functional within objects? Or, is it that the array is made as a class variable?

Code:
function Element() {
// INSTANCE VARIABLES
this.name = "newElement" + Element.total_elements_created; // GIVE UNIQUE NAME
// INITIALIZATIONS
Element.element_count ++; // INCREASE TOTAL NUMBER OF ELEMENTS EXISTING

[Code]...
