Any help would be greatly appreciated

$("input[name='textbox1']").blur(function() {

<p></p>
<div></div>
<script>
    $("#text1").keyup(function () {
      var value = $(this).val();
      value2 = value*2;
      value3 = value*3.7;
      $("p").text(value2);
       $("#text2").val(value3);
    });
