Google map API theme option page not displaying

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="http://ift.tt/Ylci2T"></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', trouverAdresse); 
                </script> 

So 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="adresse-hidden">
                  <?php echo "<input id='adresse' type='text' value= '{$content_options['geolocal_setting']}'/>"?>
                </form>
            </div>
