Hey, I liked the challenge, so I tried it out.

//in the head section: This function makes the text input elements depending on the number selected in the options.

<script type="text/javascript">
function makeInputs(amt){
    var str="";
    for(i=0;i<amt;i++){
        str += 
        "<input type=\"text\" name=\"text_" + 
        (i+1) + "\"" + 
        " id=\"text_" + i + "\"" +
        " value=\"\" />\n";
    }
    document.getElementById('inputs').innerHTML = str;
}
</script>

//in the body, this makes the select area on the page, also there is a div in which to show the text inputs when they are made.

<select style="width:160px;" id="text" name="participants" required="required">
<option id="" value="" name="">-Select participant-</option> 
<script type="text/javascript">
for(i=0;i<30;i++){
    document.write(
    "<option id=\"opt_" + i + 
    "\" value=\"" + i + 
    "\" name=\"opt_" + (i+1) + 
    "\" onclick=\"makeInputs(" + (i+1) + ")\">" + (i+1) + 
    "</option>\n");
}
</script>
</select>
<div id="inputs">
</div>

Hope this helps, any more questions let us know.

    $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
    if(!$link) {
        die('Failed to connect to server: ' . mysql_error());
    }

    //Select database
    $db = mysql_select_db(DB_NAME);
    if(!$db) {
        die("Unable to select database");
    }



    $user =& JFactory::getUser();
    $ID = $user->id;

    $null = null;

    $Title = mysql_real_escape_string($_POST['Title']);
    $participants = mysql_real_escape_string($_POST['participants']);
    $Email= mysql_real_escape_string($_POST['Email']);
    $Name= mysql_real_escape_string($_POST['Name']);

$dbc = mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or
die('Unable to connect to MySql: '.mysql_error());

mysql_select_db(DB_NAME, $dbc) or
die('Unable to connect to MySql: '.mysql_error());

$reg = "INSERT INTO jkhlc_registrationT values
