IF you want to show the current selection of the select box before submitting the form it. Then you'll want to look into Javascript to get the current selected value fo the selectbox.

Something like this:

if (!isset($_POST['submit']))

<script type="text/javascript">

function getEdu(eduValue)
    //alert('Form has changed: value = ' + eduValue);
    eduText.innerHTML = "You have selected: " + eduValue;

<div id="eduText">Make a selection below:</div><br />
<form method="post" action="<?php echo $_SERVER['PHP_SELF'];?>" onChange="getEdu(document.getElementById('edu').value)">
  <select name="education" id="edu">
    <option value="Jr.High">Jr.High</option>
    <option value="HighSchool">HighSchool</option>
    <option value="College">College</option>
  </select>:<br />
<input type="submit" value="submit" name="submit"><br />
</form><br />
    echo $_POST['education'];

You cant do that you will [b]HAVE[/b] to submit the form in order for PHP to create the $_POST['education'] variable this will then hold value fo the option that was selected upon submit. PHP will create this variable automatically.

Why do want PHP to create the variable before you submit the form?, as this is impossible to do

Well in that case you will want to look in to AJAX and PHP for what you want to do. As you can't do what you want to do with just PHP on its own. Have a look at the [a href=\"http://www.ajaxfreaks.com/tutorials/1/0.php\" target=\"_blank\"]AJAX Tutorial[/a] over at ajaxfreaks.com.

NOTE: You can get help over at ajaxfreaks.com on the AJAX forum no need to signup again to that forum over at ajaxfreaks.com as your account which you use here should work over there as both forums are tied to the same database.
