hello..
please help me on this:

$sel = “select count(A.club) from student A, school B WHERE A.loginID = B.loginID”;
$sel_res = mysql_query($sel) or die(mysql_error($sel));

while ($rs = mysql_fetch_assoc($sel_res)){
if($rs[“category”]!==”Normal”){
foreach($rs as $column){ echo $column; }
}
}

[COLOR=Red]if($rs[“category”]!==”Normal”)
[/COLOR]
