[jQuery] jQuery submission / IE6 problems

[IanDev]

Hi All,

I'm having problems getting a simple poll to work correctly in IE6 -
unfortunatey the form always trys to submit, ignoring the jQuery
(1.2.6)
script below:

$(function() {
 $('.error').hide();


 $("#button").click(function() {
   $('.error').hide();

         var pollid = $('#pollid').val();

               var ansa;
               var ansb;

               if ($('#ansa:checked').val() == null) {
                       ansa = "";
                       poll = "ansB";
               }

               if ($('#ansb:checked').val() == null) {
                       ansb = "";
                       poll = "ansA";
               }
               /*
               if (ansa != "" || ansa != "undefined")
               {
               poll = "ansA";
               }

               if (ansb != "" || ansb != "undefined")
               {
               poll = "ansB";
               }
               */
               var dataString = 'ans='+ poll + '&pollid=' + pollid;;
               //alert (dataString);return false;

               $.ajax({
     type: "POST",
     url: "poll-process.htm",
         cache: false,
     data: dataString,
     success: function(html) {

       $('.poll-container').html("<div id='message'></div>");
       $('#message').append(html)
       .hide()
       .fadeIn(1500, function() {
         $('#message');
       });
     }
    });
   return false;
       });
});

The HTML is as follows:

<form id="poll" name="vote" action="" method="get">
<h3>What's the best way out of the recession?</h3>
<p><input type="hidden" id="pollid" name="pollid" value="59762" />
<input type="radio" name="poll" id="ansa" value="ansA">Spend more
money</input><br />
<input type="radio" name="poll" id="ansb" value="ansB">Cut down on
expenses</input><br />
<input id="button" class="button" type="submit" value="Vote" /></p>
</form>

I'm quite new to jQuery so any help would be greatly appreciated,
thanks in advance.
