Solved: Can someone please see what I am doing wrong with my JS literal object

I get the following error when I run the code below:

Customer is not a constructor cust1 = new Customer();

<html>
<head><title>Object object</title>
<script type="text/javascript">

var Customer = {
            name : undefined,
            gender : undefined,
            photo : undefined,
            occupation : undefined,

            setName : function(name) {
                  this.name = name;
            },
            setGender : function(gender) {
                  this.gender = gender;
            },

            setPhoto : function(photo) {
                  this.photo = photo;
            },

            setOccupation : function(occupation) {
                  this.occupation = occupation;
            },

            getName : function() {
                  return this.name;
            },

            getGender : function() {
                  return this.gender;
            },

            getPhoto : function() {
                  return this.photo;
            },

            getOccupation : function() {
                  return this.occupation;
            },

            showCustomer : function() {
                  var table = "<table border='1'><th>Customers</th>";
                  table += "<tr><td>Name : </td><td> " + this.getName() + "</td></tr>";
                  table += "<tr><td>Gender : </td><td> " + this.getGender() + "</td></tr>";
                  table += "<tr><td>Photo : </td><td> " + this.getPhoto() + "</td></tr>";
                  table += "<tr><td>Occupation : </td><td> " + this.getOccupation() + "</td></tr>";
                  table += "</table>";
                  document.write(table);
}}

</script>
</head>
<body bgColor="#EOFFFF">
<script type="text/javascript">

cust1 = new Customer();
cust1.setName(prompt("Please enter the name here",""));
cust1.setGender(prompt("Please enter the gender here",""));
cust1.setPhoto(prompt("Please enter the photo here",""));
cust1.setOccupation(prompt("Please enter the occupation here",""));
cust1.showCustomer();
</script>
</body>
</html>

Can someone please advise what I am doing wrong?
