Return function ERROR MESSAGE

1

Okay, I am getting this error message. I have fixed this on a different function, but I don’t know what to do here.

Here is the error message

Fatal error:  Call to a member function on a non-object in /homepages/18/d166983733/htdocs/admin/newclientinfo.php on line 22

Here is line 22

return($result->fetch_assoc());

Here is the function in which this code is found

function get_clientrec_record($clientrec)
{
  $query = "select * from clienttable where id = '$clientrec'";
  $result = mysql_query($query, $handle);
  return($result->fetch_assoc());
}
