What's wrong here? The alert function was working until I added this new function to it.

Is there anything I am doing wrong? It just simply doesn't fire the alert anymore.

<input value="1"  type="checkbox" name="salgsvilkar" id="checkbox2"  style="float:left;"
        />

    {literal}
             <script src="http://code.jquery.com/jquery-latest.js"></script>
                <script type="text/javascript">
    $(function() {
       //checkbox
       $("#scrollwrap").click(function(){
        $("#scrollwrap").toggleClass('highlight');
        });?
    });

    $(function(){
       //button
       $("#fullfor_btn").click(function(e){
           if(!$("#checkbox2").is(':checked') == false)
           {
               alert("Please accept the terms of sale."); 
               e.preventDefault();
           }
       });
     });
    </script>
      {/literal}


<button type="submit" class="submit" name="{$method}" id="fullfor_btn" title="Fullfør bestillingen nå" value="">&nbsp;</button>
