Can't get checked value of checkbox

[Fiqhi]

function checker(file,type) {
	var mail_tot;
alert("Step 1"); 
	$("input[name='mchk[]']:checked").each(function() {
alert("Step 2"); 
		var sel_mail=$(this).val();
		if((mail_tot=='')||(mail_tot=='undefined')){
			mail_tot = sel_mail;
		}else{
			mail_tot = sel_mail+','+mail_tot;
		}
	});
	var a=$.get("invite_stat.php", {
		mail_tot:mail_tot,type:type},
		function(data){
			ShowSearch('',file);
                       
		}
	);
}

When i execute that script popup "Step 1" shows up. but Step 2 didn't

I need that function to retrieve value of checked checkbox

<input id="mchk" name="mchk" type="checkbox" value="86">
<input id="mchk" name="mchk" type="checkbox" value="85">

Well, your is still named "mchk" and not "mchk[]" as you have in the selector...
