jQuery Ajax function not working

I am trying to use this code, a variation of which I have used successfully in the past, and I can't get it to work. I assume there must be some syntax or logic error that I can't find. Perhaps your eyes can discover it.

<script type=\"text/javascript\">

$(function(){
      var vehicle = $("#vehicle");
      var pickup = $("#PICKUP");
      var error = $("#error");
      var postwrap = $("#postwrap");
      $("#vsearch").submit(function(){
            if((pickup.val() == "") || (dropoff.val() == "")){
                  error.text("The post must have both a pickup and a dropoff location").fadeIn(300).delay(900).fadeOut(300);
                  return false;
                  }
            else{
                  $.ajax({
                        type: "POST",
                        url: "AJAX_process.php",
                        data: "vehicle="+vehicle.val()+"&pickup="+pickup.val()+"&add=true",
      success:
      function(r){
      postwrap.html(r);
      postwrap.hide().show(1000);$("#success").text("Post added").fadeIn(300).delay(900).fadeOut(300),
},
      error: function(){$("#error").text("Could not add post").fadeIn(300).delay(900).fadeOut(300)}
                  });
                  return false;
                  }
      }
)});
</script>

The form has the id of vsearch.

With this installed, and the form statement as simple as <form id="vsearch"> (no action statement), the form still refreshes and does not show the result in the divs

I have jQuery running OK on the page, powering some other functions. I am using it in som PHP code.

Any ideas?
