    I'm having a problem creating a Javascript form. Can someone tell me what wrong?

    Code HTML4Strict:
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" 
    <html xmlns="" xml:lang="en" lang="en">

    window.alert("You must enter a numeric value!");
    return false;
    return true;
    function calculate() 
      var shipping = 0;
      var total = 0; {
      if (document.forms[0].hand_tool.value != document.forms[0].hand_tool.value == true)
        (document.forms[0]item1.value == 20); {
      && document.forms[0].shipping.value == (shipping + 5); {
      && (document.forms[0].total.value = document.forms[0].hand_tool.value + document.forms[0].shipping.value)
    function confirmSubmit() {
      if (document.forms[0].first_name.value = "null") {
      window.alert("You have not entered the requested Customer Information.");
      return false;
      else if (document.forms[0].last_name.value = "none" || document.forms[0].city.value = "" || document.forms[0].state.value = "none") {
      window.alert("You have not entered the requested Customer Information.");
      return false;
      var pmntMethod = false
      for (var j=0; j<3; ++j) {
          if (document.forms[0].credit_card[j].checked == true) {
              pmntMethod = true;

    The calculate function is missing an opening brace for the function, and the code inside the calculate function is severely broken.
