Kondisi else if pencarian data

saya punya kode untuk pencarian data menggunakan kondisi else if, masalah nya ketika saya memberikan kondisi else dimana pada saat pencarian data tidak ada, malah else error, siapa tau ada yang tau..

if(isset($_REQUEST['customer']) && $_REQUEST['customer']<>""){
//        jika ada kata kunci pencarian (artinya form pencarian disubmit dan tidak kosong)
//        pakai ini
								$customer=$_REQUEST['customer'];
								$reload = "menu2.php?pagination=true&customer=$customer";
								$sql =  ("select ci_id,ci_name,cp_cid,cp_mate,cp_hues,cp_width,cp_mode,cp_name,cp_unit,cp_cury,cp_pack,cp_price,cp_date, cp_weight,cp_cprice,cp_uprice,cp_temp FROM [cust_pric] left join [cust_defi] on cd_cid = cp_cid join [appl_empl] on ae_id = cd_sm join [cust_info] on cp_cid = ci_id   where  cp_flag='0' and cp_cid like '%".$customer."%' ");

$result = mssql_query($sql);


}elseif (isset($_REQUEST['material']) && $_REQUEST['material']<>"") {
