I'm try to redirect to another page with multiple session variables. However i can only achieve this with one variable. Below is the code i am using:

```
<?php
session_start();
if (isset($_GET["Coid"])) {
$_SESSION["Coid"] = $_GET["Coid"];
};
if (isset($_GET["Cid"])) {
$_SESSION["Cid"] = $_GET["Cid"];
};
if (isset($_GET["Rid"])) {
$_SESSION["Rid"] = $_GET["Rid"];
};
header('Location: http://www.example.com/Admin/Home.php?Cid='.$_SESSION["Coid"]);
die();
?>

```

The above works as intended, however how would i go about adding another session variable to it ? 

Thanks.
