Marker content (infoWindow) Google Maps

Question

I'm trying to add infoWindow's to multiple markers on a Google Map. The closest I have come is to get an infoWindow to display the last address you can see in the array, on all markers. The bit of code I have pasted below does not work, I get an "Uncaught TypeError: Cannot read property '4' of undefined". I'm sure this is a scope issue, but I'm going round in circles here and could do with some help:

var hotels = [
            ['ibis Birmingham Airport', 52.452656, -1.730548, 4, 'Ambassador Road<br />Bickenhill<br />Solihull<br />Birmingham<br />B26 3AW','(+44)1217805800','(+44)1217805810','info@ibisbhamairport.com','http://www.booknowaddress.com'],
            ['ETAP Birmingham Airport', 52.452527, -1.731644, 3, 'Ambassador Road<br />Bickenhill<br />Solihull<br />Birmingham<br />B26 3QL','(+44)1217805858','(+44)1217805860','info@etapbhamairport.com','http://www.booknowaddress.com'],
            ['ibis Birmingham City Centre', 52.475162, -1.897208, 2, 'Ladywell Walk<br />Birmingham<br />B5 4ST','(+44)1216226010','(+44)1216226020','info@ibisbhamcity.com','http://www.booknowaddress.com']
        ];

        for (var i = 0; i < hotels.length; i++) {
            var marker = new google.maps.Marker({
                position: new google.maps.LatLng(hotels[i][1], hotels[i][2]),
                map: map,
                icon: image,
                title: hotels[i][0],
                zIndex: hotels[i][2]
            });

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

            google.maps.event.addListener(marker, 'click', function () {
                var markerContent = hotels[i][4];
                infoWindow.setContent(markerContent);
                infoWindow.open(map, this);
            });
        }

Thanks in anticipation.

We've solved this, although we didn't think having the addListener outside of the for would make any difference, it seems to. Here's the answer:

Create a new function with your information for the infoWindow in it:

function addInfoWindow(marker, message) {

            var infoWindow = new google.maps.InfoWindow({
                content: message
            });

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

Then call the function with the array ID and the marker you want to create:

addInfoWindow(marker, hotels[i][3]);
