require_once ("check.php");
createsessions($username,$password,$userid,$projectid,$projectname,$filename,$size,$allocatedmemory,$answer,$usedmemory);
$con=mysql_connect("10.70.1.248","invensis","invensis");

VALUES ('$_POST[projectname]','$_POST[allocatedmemory] $_POST[size]','$_SESSION[username]')";
echo "New Project Added";
if(!mysql_query($sql,$con))
 {
 	die('Error:' . mysql_error());
 }
}

Hi,
In u r code

$_SESSION[usedmemory] < $_SESSION[allocatedmemory]

change it as

$_SESSION['usedmemory'] < $_SESSION['allocatedmemory']

and use echo to see u get all the values

echo $_SESSION['usedmemory'] ;
echo $_SESSION['allocatedmemory'];

thx u,
Prem
