syntax error, unexpected }

[joecooper]

i get the unexpected } on line 20, but cant see whats wrong as it should be there to end the IF command

 

<?php

if (isset($_POST['submit'])){ //if page was accessed via submit
    $username=$_POST['username']; //set username varible to the username they entered
    $password=$_POST['password']; //set password varible to the password they entered

    if($username){ //check that username feild was entered
        if($password){ //check that password feild was entered
            $password=md5("123$password"); //encrypt thier password to compare

            $result=mysql_query($sql);
            //If the user gets to here, then they have typed both a username and password, so we may now go onto finding out if they excist in the DB
            $sql="SELECT * FROM users WHERE (username='$username') AND password='$password'"; //get rows where the username feild matches the username feild in the database with same password
            $result=mysql_query($sql);

            if (mysql_num_rows($result) > 0){ //if the number of rows returned is more then 1, then the details excist
                echo("Welcome $username!, you are now logged in!");
                $_SESSION['loggedin']="TRUE";
                $_SESSION['username']=$username
            }
        }else{
            echo("Please enter your password");
        }
    }else{
        echo("Please enter your username");
    }
} //page freshly accessed... do nothing!

?>

<form method="POST" action="register.php">
      Username: *<input type="text" name="username" size="20" value="<?php echo $username; ?>" maxlength="255"><br>
      Password: *<input type="password" name="password" size="20" value="" maxlength="255"><br>
