need help with session

[Alidad]

hi, I'm trying to create upload profile forms using dreamweaver.
My first step is that i created login forms in "login.php" and works great with mysql database to log in.
In that forms i created session variables for user name from databse. which is

<?php 
session_start(); 
?>
.
.
.
.
$_SESSION['MM_Username'] = $loginUsername;

.

and then it redirect to "member.php" page after loged in.
in that page i created

<?php 
session_start(); 
?>
.
.
.
<?php echo $_SESSION['user_name']; ?>
.
.
.

but is not showing the user name, does anyone tell me what did i missed part this code and why is not showing user name!

If you are doing a header() redirect, you may need to do is a [man]session_write_close/man before you do the header() redirect call.

I hope that

$_SESSION['MM_Username'] = $loginUsername;

Is in between some <? and ?> tags otherwise that's a HUGE problem right off the bat. Not to mention you are trying to echo $SESSION['user_name']; which is not the variable you set. It would be $SESSION['MM_Username'];
