    Question Hidden Text Field and process page help.

    I need for the form to do the following:
    when age is greater than or equal to 65 enter "yes" in the hidden field
    when age is less than 65 enter "no" in the hidden filed
    return true

    Create a page processAge.htm that
    Writes the message on the page
    Hi name. At age # you may retire.
    Hi name. At age # you are not ready to retire. Get to work.
    name is the name entered on the form.
    # is the age entered on the form.

    <script type="text/javascript">
    /* <![CDATA[ */
    function validateSubmission() {
      var retValue = true;
      if (document.forms[0].name.value == "") {
          window.alert("You did not fill in one of the following required fields: Name or Age.");
          retValue = false;
    function checkForNumber(fieldValue) {
      var numberCheck = isNaN(fieldValue);
      if (numberCheck == true) {
        window.alert("You must enter a numeric value!");
        return false;
    /* ]]> */
    <form action="processAge.htm" method="get" onsubmit="makeList(); return validateSubmission(); ">
    <table frame="border" rules="cols" >
    <td valign="top">
    <p>Name<br />
    <input type="text" name="name" size="40" /></p>
    <p>Age<br />
    <input type="text" name="age" size="40" onchange="return checkForNumber(this.value);" /></p>
    <p style="text-align: center"><input type="submit" value="Send" /><input type="reset" />
    <input type="hidden" name="Retirement" /></p>
    Process Page:
    <script type="text/javascript">
    /* <![CDATA[ */
    document.write("<h1>Your form has been submitted!</h1><h2>You entered the following data:</h2>");
    var formData = location.search;
    formData = formData.substring(1, formData.length);
    while (formData.indexOf("+") != -1) {
      formData = formData.replace("+", " ");
    formData = unescape(formData);
    var formArray = formData.split("&");
    for (var i=0; i < formArray.length; ++i) {
      document.writeln(formArray[i] + "<br />");
    /* ]]> */
    Thanks for any help!

    First off outofcrayons, you have no 'value' set in the hidden field, so you can't change it. The line S/B <input type="hidden" name="Retirement" value="maybe" />.

    Next: Your using the $_GET method to send form info. You should send it to a php file for processing not a html file. To make sure your form works start with this php
    echo 'the php file<br />';
    echo $_GET["name"], '<br />';
    echo $_GET["age"], '<br />';
    echo $_GET["Retirement"], '<br />';
    Lastly Your javascript for checking the form and then submitting it should be one function and should be called from the submit button. Google it.
