Pop-up info box in google maps

I have the following code and would like some help adding pop-up info boxes for each custom marker. Currently I can set the coordinates for each marker in my code but I would also like to add additional information in a pop-up info box once the marker is clicked. I cant seem to get a pop-up info box to work

You'll want to read this: https://developers.google.com/maps/documentation/javascript/infowindows

Steps below with comments:

Construct an infoWindow object new google.maps.InfoWindow()
In the creation of each marker bind a click event to that marker. Pass at a minimum, the marker you created to that callback through a closure.
The callback will setContent of the infoWindow. You'll probably want to dynamically create an html string and send it to setContent
The callback will then open the info on the map over the clicked marker

Just declared variable infoWindow above addMarker and in its actionListener opened and set the content for infowindow

 google.maps.event.addListener(marker, 'click', function() {
           infoWindow.setContent('Hi');
           infoWindow.open(map,this);
        });

check out:

    var map; // google map object
    var markers = []; // we well store the markers here 


    function initialize() {
      map = new google.maps.Map(document.getElementById('map_canvas'), {
        zoom: 6,
        center: new google.maps.LatLng(-41.269954, 174.225516),
        mapTypeId: google.maps.MapTypeId.TERRAIN,



        <!-- Let's style the map with custom colours and opacity -->	  

        styles: [{
          featureType: 'poi.business',
          elementType: ' labels.icon',
          stylers: [{
            visibility: 'on'
          }, {
            hue: '#ff00db'
          }, {
            lightness: 0
          }, {
            saturation: 0
          }]
        }]
      });



      <!-- create KML layer -->

      var myKmlOptions = {
        preserveViewport: true,
        suppressInfoWindows: true
      }

      var kmlLayer_1 = new google.maps.KmlLayer("http://private.aatravel.co.nz/accommodation/1038668/proof14/final.kml", myKmlOptions);
      var kmlLayer_2 = new google.maps.KmlLayer("http://private.aatravel.co.nz/accommodation/1038668/proof14/sep.kml", myKmlOptions);
      kmlLayer_1.setMap(map);
      kmlLayer_2.setMap(map);
