I need help for a feature

[Adem]

Hello,

My code:

<script type="text/javascript">
function baslangic(status)
{
status=!status;    
textler=document.getElementsByName("secilen_receiver_sayisi[]");
for(x=0;x<textler.length;x++){
textler[x].disabled = status;
}
}

function isaretle(){
marka=document.getElementsByName("secilenreceivermarka_id[]");
sayi=document.getElementsByName("secilen_receiver_sayisi[]");
for(x=0;x<marka.length;x++){
sayi[x].disabled=!marka[x].checked;
}
}

function kontrol(){

marka=document.getElementsByName("secilenreceivermarka_id[]");
sayi=document.getElementsByName("secilen_receiver_sayisi[]");
for(x=0;x<marka.length;x++){
if(marka[x].checked==true&&(sayi[x].value><?=$maximum_receiver?>||sayi[x].value==""||sayi[x].value<1||sayi[x].value.search(/\d/g)<0)){

alert("Receiver seçme isteğe bağlıdır.\n\nEğer bir marka seçtiniz ise miktarıda seçmelisiniz ve toplam daire sayınız olan <?=$maximum_receiver?> adet geçmemeniz gerekiyor.");

return false;
}
}
return true;
}
</script>

This is the name of Checkbox : name="secilenreceivermarka_id[]"
This is the name of Select list: name="secilen_receiver_sayisi[]"
Maximum amount variable: <?=$maximum_receiver?>
