Java script error on Safari and Chrome

Question

I have a function that opens a popup menu. but on safari and Chrome i get this error but on IE it works fine. it looks like these browsers do not recognise ".document" im guessing. does any one know what the cause of it is?

Error on Safari:

TypeError: Result of expression 'addressPopupMenu' [undefined] is not an object.

Error on Chrome:

Uncaught TypeError: Cannot read properties 'document' of undefined.

The function:

var addressPopupMenu = window.createPopup();



function showAddressPopup() {

        if(isDroppedDown == 0){

        var addressPopup = document.getElementById('addressFullSpan');

        addressPopupMenuBody = addressPopupMenu.document.body;

        addressPopupMenuBody.style.backgroundColor = "#29527A";

        var height = 0;
        var width = 0;

        if (addressPopup.innerHTML != '') {

            addressPopupMenuBody.innerHTML = addressPopup.innerHTML;

            if (addressPopupMenu.isOpen) {

                addressPopupMenu.hide();

            }

            addressPopupMenu.show(0, 0, 0, 0);

            height = addressPopupMenuBody.scrollHeight;

            width = addressPopupMenuBody.scrollWidth;

            addressPopupMenu.hide();

        } else {

            height = 0;

            width = 0;

        }

        var widthForResolution = 299;

        if (screen.width<=1024){

            widthForResolution = 235;

            }

        if(screen.width>=1280){

            widthForResolution = 299;

            }


        var link0 = document.getElementById('Pname');

        addressPopupMenu.show(84 , 105 , widthForResolution, 140, addressPopup); //left , top + width, height

        }

    }

window.createPopup() is a IE only function
