hola sandrox23...
Primero por supuesto debiste haber creado la variable sesión a través de un FORM de LOGIN, y la variable sesion pudiste haberla puesto en una variable como esta:
$_SESSION['s_username'] = $row["nick"];//acá por supuesto debiste haber corroborado datos de contraseña y usuario (creo que estás haciendo políticas de usuario). Además también debiste haber chequeado que el USER y el password son correctos para crear la sesion con su nombre por ejemplo
..........................
espero te sirva .. salu2
