Boa noite;

tenho aqui um codigo para o painel de administração do meu site, onde o administrador ve os utilizadores inscritos no site, mas esta-me a dar os seguintes erros:

Notice: Undefined index: flag in C:\xampp\htdocs\LAYOUT\cpanel\utilizadores.php on line 83

Notice: Undefined index: flag in C:\xampp\htdocs\LAYOUT\cpanel\utilizadores.php on line 88

O codigo é o seguinte:

<html>
<head><title></title>

<script>
function checkButton(reg){

var chcks = document.getElementsByName("alunos[]");
for(var i=0; i  < chcks.length; i++){
	if (reg.checked==true){
		chcks[i].checked=true;
	}else{
		chcks[i].checked=false;
	}
}

}

function actDesact(op){

var checks = document.getElementsByName('alunos[]');

for(var i=0; i < checks.length; i++){
	if (op==1){
		checks[i].checked=true;
	}else if(op==0){
		checks[i].checked=false;
	}
}	
}
</script>

</head>
<body>
