Why is this not working right?

[clamum]

See my code below. The part that's stumping me is why the

echo "session: " . $_SESSION["photo$cntn"] . ", " . $_SESSION["photo$cntu"] . "<br />";

line prints out the same name for both session variables. It's as if $_SESSION["photo$cntn"] was replaced with $_SESSION["photo$cntu"] in that line.

What's weird is that

echo $name . "<br />";
$_SESSION["photo$cntn"] = $name;
echo $unique_name . "<br />";
$_SESSION["photo$cntu"] = $unique_name;

Prints out correctly, i.e., the $_SESSION["photo$cntn"] and $_SESSION["photo$cntu"] are different like they should be. I'm trying to save the original filename and a uniquely generated (using the md5(uniqid(time())) function) filename in session variables and this has got me stumped. I must be missing something obvious but I don't know what it is. Any help would be appreciated.

Here's what gets printed out:
