Hello I am pleased if someone could explain me the behaviour since is wrong the following function call: ($row = & $result->fetchRow(DB_FETCHMODE_ASSOC, $_SESSION["searchFormVars"]["offset"]+$rowCounter)); as you will find them on the bottom of the email. By the way, fetchRow() is a method from class DB(.php). However mysql_fetch_row() should have same functionality but the argument resp. the identity is different. I hardly try to do not mix up functionality from mysql- with db- members. mysql_select_db("knowledge", $link); $query = setupQuery($_SESSION["searchFormVars"]["search"]); for ( $rowCounter = 0; ($rowCounter < SEARCH_ROWS) && (( $rowCounter + $_SESSION["searchFormVars"]["offset"]) < mysql_num_rows($result)) && ($row = & $result->fetchRow(DB_FETCHMODE_ASSOC, $_SESSION["searchFormVars"]["offset"]+$rowCounter)); $rowCounter++) { Error message: Fatal error: Call to a member function fetchRow() on a non-object in C:\Xampp\xampp\htdocs\www2\knowledge_db\searchnew.php on line best regards, Georg
