Google map API theme option page not displaying - function

Question

I'm having some issues with the integration of a google map in my web site which can geocode an address before displaying the map with the correct location.
So i have a script (it worked when i was in localhost but since i put the web site online nothing happens) :
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
<script>
var geocoder;
var map;
var firstLoc;
function findAddress() {
geocoder = new google.maps.Geocoder();
geocoder.geocode( { 'address' : document.getElementById('address_field').value},
function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
firstLoc = results[0].geometry.location;
map = new google.maps.Map(document.getElementById("map-location"),
{
center: firstLoc,
zoom: 17,
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var marker = new google.maps.Marker({
map: map,
position: results[0].geometry.location
});
}
else {
alert('Geocode failed: ' + status);
}
}
);
}
google.maps.event.addDomListener(window, 'load', findAddress);
</script>
I put an address in a field in my theme option page then i register the value and put it in a hidden input in my front-end and try to get it with geocoder.geocode( { 'address' : document.getElementById('address_field').value}
Seems to have a problem with geocoding, i tested with a simple script with a fix position and it showed fine.
In case you need it this is how i display the map in the front-end :
<div class="contact-map">
<div id="map-location"></div>
<form class="address-hidden">
<?php echo "<input id='address_field' type='text' value= '{$content_options['geolocal_setting']}'/>"?>
</form>
</div>
