Hello,I'm new to Umbraco and am trying to find my way around.I was asked to add this code to the head tag, however, I do not see it in the master file for the page.  How do I add it without breaking the page, because that's what happens when I try.Here's the code I'm trying to add to the head tag:<link rel="canonical"href="http://online.saintleo.edu/the-saint-leo-experience/online-degree-programs.aspx" />Here's my master page code:<%@ Master Language="C#" MasterPageFile="~/masterpages/Main.master" AutoEventWireup="true" %><%@ Register Namespace="UmbracoBreadcrumb" TagPrefix="Crumb" %><script runat="server">    int b = 0;    int degreeCount = 0;    protected void Page_Load(object sender, EventArgs e)    {        XmlNodeList degrees = UmbracoItem.CurrentPage.SelectNodes("DegreeRouterPage");        degreeCount = degrees.Count;        b = degreeCount % 2 == 0 ? degreeCount / 2 : (degreeCount / 2) + 1;        DegreeRepeater.DataSource = degrees;        DegreeRepeater.DataBind();    }</script><asp:Content ID="Content1" ContentPlaceHolderID="PageStyles" runat="server"><style>#scenic-bg{ background-color: #<%=XPathBinder.Eval(UmbracoItem.CurrentPage, "ancestor-or-self::* [@level='2']/scenicBackgroundColor") %>; background-image: url(<%=XPathBinder.Eval(UmbracoItem.CurrentPage, "ancestor-or-self::* [@level='2']/scenicBackgroundImage") %>); background-position: 50% 0; background-repeat: no-repeat;}</style></asp:Content><asp:Content ID="Content2" ContentPlaceHolderID="PageScripts" runat="server"> <script type="text/javascript" src="<%=VirtualPathUtility.ToAbsolute("~/scripts/libs/jquery.color.js") %>"></script></asp:Content><asp:Content ID="Content3" ContentPlaceHolderID="BackgroundScene" runat="server"><div id="scenic-bg"></div></asp:Content><asp:Content ContentPlaceHolderID="MainContent" runat="server"><div id="page-body" class="inner standard">    <div id="primary-content">        <Crumb:UmbracoBreadcrumbMenu CssId="breadcrumb-navigation" ShowRootNode="true" RootNodeTitle="Home" ShowCurrentNode="true" LinkCurrentNode="false" ID="breadcrumb" runat="server"></Crumb:UmbracoBreadcrumbMenu>        <% if (!string.IsNullOrEmpty(UmbracoItem.Get("academicsRouterBillboardPhoto"))) { %>        <div class="billboard">            <div class="copy-container">                <p class="marketing-headline tk-ff-meta-web-pro"><strong><umbraco:Item Field="academicsRouterBillboardPhotoHeadline" runat="server" /></strong></p>                <p class="marketing-copy"><umbraco:Item Field="academicsRouterBillboardPhotoCopy" runat="server" /></p>                <% if (!string.IsNullOrEmpty(UmbracoItem.Get("academicsRouterBillboardPhotoLink")))                   { %>                <p class="learn-more"><a href="<%=umbraco.library.NiceUrl(Convert.ToInt32(UmbracoItem.Get("academicsRouterBillboardPhotoLink"))) %>"><umbraco:Item Field="academicsRouterBillboardPhotoLinkText" runat="server" /></a></p>                        <% } %>            </div>            <img class="billboard-photo" src="<%=UmbracoItem.Get("academicsRouterBillboardPhoto") %>" alt="<%=UmbracoItem.Get("academicsRouterBillboardPhotoAltText") %>" />        </div>        <% } %>        <div class="line">            <div class="inner">            <h1 class="tk-ff-meta-web-pro"><umbraco:Item Field="pageName" runat="server" /></h1>            <% if (!string.IsNullOrEmpty(UmbracoItem.Get("academicsRouterIntroCopy")))            { %>            <p><umbraco:Item Field="academicsRouterIntroCopy" runat="server" /></p>            </div>            <% } %>        </div>        <hr class="star" />        <div class="line router-sub">        <asp:Repeater ID="DegreeRepeater" runat="server">            <HeaderTemplate>                <div class="col half">                    <div class="inner">            </HeaderTemplate>            <ItemTemplate>                <asp:PlaceHolder id="P1" runat="server" visible='<%#Container.ItemIndex > 0 && Container.ItemIndex % b == 0 && Container.ItemIndex != degreeCount - 1%>'>                    </div>                </div>                <div class="col half<%#Container.ItemIndex / b == 2 ?
