infowindow help on google map

Hi, I am using Advanced Custom Fields to set the location of a post and display it on a map within my custom post template and it works great. But I have also created a google map that plots all the locations of my custom posts types on one map.

My problem is that I can’t get it to pull content or a link into the infowindow. I’ve looked around the internet and tried to use the code that google suggests as well as the users on this site, but I seem to be doing something wrong. All it does is display the title followed by a weird symbol. Any help would be appreciated 🙂

This is the code I am using:

<section>

<?php
  $args = array(
	  'post_type'		=> 'offices',
	  'posts_per_page'	=> -1
  );
// query
$wp_query = new WP_Query( $args );
$NUM = 0;
?>

  <div id="map"></div>

<script src='http://maps.googleapis.com/maps/api/js?sensor=false' type='text/javascript'></script>
<script type="text/javascript">
    var locations = [<?php while( $wp_query->have_posts() ){
	$wp_query->the_post();
    $location = get_field('location'); // IMPORTANT << Change this for your Google map field name !!!!!!
?>

['<?php the_title(); ?>',   <?php echo $location['lat']; ?>, <?php echo $location['lng'];?>, <?php $NUM++ ?> ],
   <?php } ?> ];

    var map = new google.maps.Map(document.getElementById('map'), {
      zoom: 7, /*Here you change zoom for your map*/
      center: new google.maps.LatLng(42.6, -76.0), /*Here you change center map first location*/
       mapTypeId: google.maps.MapTypeId.ROADMAP
    });

    var infowindow = new google.maps.InfoWindow();

	
	
    var marker, i;

    for (i = 0; i < locations.length; i++) {
      marker = new google.maps.Marker({
        position: new google.maps.LatLng(locations[i][1], locations[i][2]),
        map: map
		
      });

      google.maps.event.addListener(marker, 'click', (function(marker, i) {
        return function() {
          infowindow.setContent(locations[i][0]);
          infowindow.open(map, marker);
        }
      })(marker, i));
    }

 </script>
</section>
