For a multiple elements with same name, the element becomes
collection. It can be accessed like an array. Use some code like:

function verif_champs(f)
{
var z=f.elements['Genre'];
var y=z.length;
while (y--)
{
if (z[y].checked)
{
return true;
}
}
alert('choose genre');
return false;
}

The form declaration should give parameter to the new function

<form name="forml" method="post" onSubmit="return verif_champs(this)"
action="test22.php" >
