Azure Mobile Services in HTML

How can I implement my Windows Azure Mobile Services in an HTML page??

I tried the code snippets that are present in the Azure portal but it just didn't work..

The code snippets that they ask me to put in my HTML page are:

    <script src="http://ift.tt/187JuXj"></script>

and

var client = new WindowsAzure.MobileServiceClient("key1", "key2");

Then when I try to insert a record into the database I use this code:

var get_table = client.getTable("People");
get_table.insert({ FirstName: "Marwan", LastName: "Younis" });
