session problem

[mikefn]

Hi,

I want to have one link that have several options.
Here is the example:

test1.php:
<?php

session_start();
session_register('filename');

$URL1 = "name.php";
$URL2 = "address.php";
$URL3 = "sex.php";

$filename = $URL1;
echo "<a href=main.php>Name</a>";

$filename = $URL2;
echo "<a href=main.php>Address</a>";

$filename = $URL3;
echo "<a href=main.php>Sex</a>";
?>

main.php:
<?php
session_start();

echo "$_SESSION[filename]<br>";
// include "$_SESSION[filename]";

?>

Now the problem is either the user click on Name, Address, or Sex link, the're all going to the last one (Sex link).
Anyone could help me?
Thanks.
