Google maps marker, with added directions code not showing - google-maps

Question

I seem to be having trouble adding a marker to one of my maps that I have created and I just can't seem to figure out where I am going wrong with it.
The map has been added to the site fine, and I even have the directions code working which happens to be displaying markers.
What I would like would be an initial marker to display where, in this case, the school is and have an info box on click to show the address but I just can't seem to get it displaying no matter what I try.
My code for everything is as follows:-
<div id="map_canvas" style="width:100%; height:392px;float:left;"></div>
<div id="directionsPanel" style="float:left;max-width:395px; overflow:scroll;overflow-x: hidden;"></div>
<script>
//define one global Object
var myMap = {}
//init
function initialize(){
//set up map options
var mapOptions = {
center: new google.maps.LatLng(53.964304,-2.028522),
zoom: 15,
scrollwheel: false,
mapTypeId: google.maps.MapTypeId.ROADMAP,
};
myMap.map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
myMap.directionsService = new google.maps.DirectionsService();
myMap.directionsDisplay = new google.maps.DirectionsRenderer();
myMap.directionsDisplay.setMap(myMap.map);
myMap.directionsDisplay.setPanel(document.getElementById("directionsPanel"));
}//end init
function createMarker(point, title, content, map) {
var marker = new google.maps.Marker({
position: point,
map: map,
title: title
});
var infowindow = new google.maps.InfoWindow({
content: content
});
google.maps.event.addListener(marker, 'click', function() {
if(curr_infw) { curr_infw.close();} // We check to see if there is an info window stored in curr_infw, if there is, we use .close() to hide the window
curr_infw = infowindow; // Now we put our new info window in to the curr_infw variable
infowindow.open(map, marker); // Now we open the window
});
return marker;
}
//directions
var calcRoute = function() {
var start = document.getElementById("start").value,
end = document.getElementById("end").value,
request = {
origin:start,
destination:end,
durationInTraffic :true,
transitOptions: {
departureTime: new Date()
},
provideRouteAlternatives : true,
travelMode: document.getElementById("travelmode").value
};
myMap.directionsService.route(request, function(result, status) {
if(status == google.maps.DirectionsStatus.OK) {
myMap.directionsDisplay.setDirections(result);
}else{
alert("something went wrong!");
}
});
}
//script loader
var loadScript = function() {
var script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://maps.googleapis.com/maps/api/js?key=AIzaSyDZsY0Xbo137bDtb8wmefTogdGl82QM85s&sensor=false&callback=initialize";
document.body.appendChild(script);
}
window.onload = loadScript;
Any help on this guys would be greatly appreciated before I end up becoming bald from pulling out all my hair lol.
