while($i <= $_SESSION['stuff'])
{
$a = $_POST["fn"."$i"]."<br />";
echo $a;
$i++;
if(isset($_POST["selected"."$i"]))
{
echo $_POST["$fn"."$i"]."<br />";
echo $_POST["$ln"."$i"];
}
}
}
}

I think you made mistake in post Variable
$_POST["$fn"."$i"] to $_POST["fn"."$i"]
if(isset($_POST["selected"."$i"]))
{
echo $_POST["$fn"."$i"]."<br />";
echo $_POST["$ln"."$i"];
}
To
if(isset($_POST["selected"."$i"]))
{
echo $_POST["fn"."$i"]."<br />";
echo $_POST["ln"."$i"];
}
