I need help with some code I wrote, can someone tell me what I did wrong, it will not work

It is a show, hide when the radio button is pushed here is the code:

HTML:

<h1>Single or Recurring Choice</h1>
<div id="payment_type">
    <strong>Please select a payment type:</strong>
    <input class="option" type="radio" name="group1" value="single" checked="checked" /> Single
    <input class="option" type="radio" name="group1" value="recurring" /> Recurring
    <input class="option" type="radio" name="group1" value=“contact" /> Contact Us
</div>
 
<div id="single">
<!-- information goes here -->
</div>
 
<div id="recurring">
<!-- information goes here -->
</div>

<div id=“contact">
<!— information goes here-->
</div>


Here is the Script:

(function($){
    $(document).ready(function(){
        $("#recurring").hide();
        $(".option").click(function(){
            var val = $(this).val();

            if(val=="single"){
                $(“#recurring, #contact").hide("slow", function(){
                    $("#single").show("slow");
                });
            } else if(val==“recurring”) {
                $(“#single, #contact").hide("slow", function(){
                    $("#recurring").show("slow");
                });
            } else {
                $(“#single, #recurring").hide("slow", function(){
                    $(“#contact").show("slow");
                });
            }
        });
    });
})(jQuery);
