If I do that then i get this error

Fatal error: Can't use function return value in write context in
myfilename line 2

What does that mean. And one more thing, on the code where it says
if( !isset( $_SESSION['userName'] ) )
Does that mean that in this code

<form name="form1" method="" action="">
the method is session?
