Whats wrong?

[Dobakat]

whats wrong here? because i get this error...
"Fatal error: Call to a member function fetchRow() on a non-object in /home/dobakat/public_html/Istariguild/phptests/member.php on line 26"

$sql = mysql_query ("SELECT User, Pass FROM members WHERE User'".$_POST['User']."'");
$check=($sql);

   if ($check->numRows() == 0) {
           die('That User does not exist in our database.');
   }

   $info = $check->fetchRow();

line is if ($check->numRows() == 0) {

mysql_query returns a result resource, not an object.
