hey guys. i have been having trouble on how to put this code into the download module. what i want it to beable to let visitors view the downloads, but not download them. so they can view the categories, click on them to get to the downloads, view the available, but when they click on them to download, it will make them sign in or register. i have been using this code for that.

global $user;
if(!is_user($user)) {
header("Location: modules.php?name=Your_Account&op=new_user");
}
