Mysqli prepare select query help!

Ok, im quite new to this prepared statement thing… i have this so far

    if ($objstmt = $objConnection->prepare("SELECT * FROM authUsers WHERE fldUsername= ? AND fldPassword= ?")) { 
    $objstmt->bind_param("ss", $this->strUsername,$this->strPassword);
      while ($objstmt->fetch()) {

but it echo’s nothing, though i do get no errors… im totally puzzled…:flower:
but obivously im doing something wrong… and the username and password is correct and inside the database
