Hello, Hans Zaunere,

Thank you very much for reply my message.

Let me tell you more detail about my pages. In my main
page called dealerorder.php, there is a link to
createTireImage.php (<a href="createTireImg.php">Click
here to create your own cover</a><br><p>). 
In createTireImg.php, code like following:
-------
<?php
include ("img_text_config.inc.php");
include ("tbContent.php");
   session_start( );
?>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0
Transitional//EN">
<html>
<head>
</head>
<body>

<form name="detail" method="post"
action="<?=$_SERVER['PHP_SELF'];?>">

<table>
<tr><td>
   <table border="1" BORDERCOLOR="blue">
      <tr><td>
      backgroud color: &nbsp;&nbsp;&nbsp;&nbsp;
      <select name="t_color">
      <?php
         if (isSet($_POST['t_color']))
            $t_color_def = ($_POST['t_color']);
         $_SESSION['t_color'] = $t_color_def;
            for ($i=0; $i <= 2; $i++)
            {
               if ($t_color_def == $i)
                  echo ("<option value=\"$i\"
selected>$color[$i]</option>");
               else
                  echo ("<option
value=\"$i\">$color[$i]</option>");
            }
      ?>
      </select>
      </td></tr>

      <tr><td>
      Text color: &nbsp;&nbsp;&nbsp;&nbsp;
      <select name="tt_color">
      <?php
         if (isSet($_POST['tt_color']))
         {
            $tt_color_def = ($_POST['tt_color']);

         }
            $_SESSION['tt_color'] =
$_POST['tt_color'];

            for ($j=0; $j <= 1; $j++)  // only need
first 2 colors
            {
               if ($tt_color_def == $j)
                  echo ("<option value=\"$j\"
selected>$color[$j]</option>");
               else
                  echo ("<option
value=\"$j\">$color[$j]</option>");
            }
      ?>
      </select>
      </td></tr>

      <tr><td>
      <input type="submit" value='Create image'
name='submit'>
      <input name="send" type="hidden" value="true">
      </td>
      </tr>

   </table>
</td>
</tr>

</table>
</form>

<a href="dealerOrder.php?backtoindex=true">Back To
Main Page</a>

</body>
</html>

-------

In img_text_config.inc.php, I defined an array:
 $color = array(0=>"Black", 1=>"White", 2=>"Tan");

After create an image, (it will show up in
dealerorder.php page), I need to describe the new
image's content including background color and text
color. You can see it in the code, i use same way to
set these two colors;
$_SESSION['t_color'] = $_POST['t_color'];
$_SESSION['tt_color'] = $_POST['tt_color'];
In dealerorder.php, i have code like below:
$message = "Image Detail:\n";
$message .= "Backgroud
color:".$color[$_SESSION['t_color']]."\n";
$message .= "Text
color:".$color[$_SESSION['tt_color']]."\n";

The error happens here. $_SESSION['t_color'] is right
(always between 0 and 2), but $_SESSION['tt_color'] is
wrong. $_SESSION['tt_color'] shows 16777215. I have
looked at $_SESSION['tt_color']'s value in
createTireImg.php before I go back to dealerOrder.php,
it was right there. After i click the click in
createTireImg.php, it changed. 

Can you figure out what's wrong with it?

Thanks again.
