When I view source of your page I see:
var address_0 = {
street: '',
city: '',
state: '',
zip: '',
country: 'USA',
infowindow: 'default',
infowindowtext: '<span style="font: 12px Verdana, Arial, Helvetica, sans-serif; color: black;"><strong>Address:</strong><br /><br />, USA</span>',
full: ', , , , USA',
isdefault: true,
addressType: 'address',
loop: '',
latitude: '',
longitude: '',
markerStyle: 'Google Traditional (pillow)',
markerColor: 'Pacifica'
};
It does not look an address has been entered.
