Dynamic Checkbox with PHP. Build an array?

$sql = "SELECT Name FROM APKs";
$resultado = mysql_query($sql) or die ("problema-- ".mysql_error());
$numero = 0;

print "<FORM NAME=\"form1\" METHOD=\"POST\" ACTION=\"index.php\">";
while($registo = mysql_fetch_array($resultado))
{
    $name = $registo['Name'];
    print "<Input type='Checkbox' Name='.$name.'>$name</br>";
    $nomes[numero] = $name;
    $numero++;
}

if (isset($_POST['Submit1'])) {

    echo $nomes[0]; // I get here a null variable
}

$name[numero] = $registo['Name'];
    print "<Input type='Checkbox' Name='.$name[numero].'>$name[numero]</br>";
    //$nomes[numero] = $name;
    $numero++;

echo "aqui" . $_POST['$name'];
