This way should work:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="JavaScript">
function Checkform()
{
var message = "";
if (document.CardForm.HoldersName.value.length == 0) {
message = message + "Please enter the name of the credit card\n";
}
if (document.CardForm.CardNumber.value.length < 16) {
message = message + "Please type in all 16 digits of the credit card number!\n";
}
else if (isNaN(document.CardForm.CardNumber.value)) {
message = message + "the Card number must contain only numbers!\n";
}
if (document.CardForm.CardMonth.value.length < 2 ) {
message = message + "Please fill in both digits for the Month!\n"
}
else if (isNaN(document.CardForm.CardMonth.value.length )) {
message = message + "The month value needs to be between 1 and 12\n"
}
else if (document.CardForm.CardMonth.value < 1 || document.CardForm.CardMonth.value >12) {
message= message + "The month value needs to be between 1 and 12\n"
}
if (document.CardForm.CardYear.value.length < 2 ) {
message = message + "Please fill in both digits for the Year!\n"
}
else if (document.CardForm.CardYear.value < 99 ) {
message = message + "The year must be greater than 99!\n"
}
if (message.length > 0) {
alert( message );
return false;
}
else { return true;
}
}
</script>
</head>

<body onLoad="document.CardForm.HoldersName.focus()">
<form name="CardForm" action="" onSubmit="return Checkform();">
