contant /

I get a couple of errors like this one for undefined variable: PHP Notice: Undefined variable: s_company_name And this one for undefined contstant PHP Notice: Use of undefined constant account_type - assumed 'account_type' I am putting a piece of code from each so that hopefully someone can explain what I need to do to correct this, I know it still runs OK, but want to eliminate error/warnings as much as possible. CONSTANT CODE: if($_POST) { if($username && $password) { f_db_open(); $q = mysql_query("SELECT * FROM uas_users WHERE user_email='$username'"); $auth = mysql_fetch_array($q); if($auth['user_password'] == $password && $auth['user_email'] == $username && $auth['account_status'] == "Approved") { $type = $auth['account_type']; mysql_query("INSERT INTO logon_log (user, date, time) VALUES ('$username', NOW(), NOW())"); f_put_cookie($auth[user_name],$auth[user_email],$auth[account_type],$auth[co mpany_name]); VARIABLE CODE: function f_option_menu($status_message ) { global $s_url, $s_logo, $s_logo_h, $s_logo_w; echo " <table border='0' width='100%' cellpadding='0' cellspacing='0'> <tr> <td> <img border=0 src='images/".$s_logo."' width=".$s_logo_w." height=".$s_logo_h."> <font face='Verdana, Arial' size='3'><b>".$s_company_name." ".$status_message."</b></font> THANKS!!!! Thanks! Jack
