Code:

<html>
<head>
<script type="text/javascript">

	function validate(nForm){

		var expires = nForm['expDate'];
		if (expires.value.length < 4 || expires.value.length > 4 || expires.value == "")
			{
			 alert('The expiration date is not 4 digits');
			 expires.value = "";
			 expires.focus();
			 return false;
			}
		var nMonth = expires.value.substring(0,2)
		var nYear = expires.value.substring(2,4);
		if (Number(nMonth) < 1 || Number(nMonth) > 12)
			{
			 alert('Invalid expiration month');
			 expires.value = "";
			 expires.focus();
			 return false;
			}
		if (Number(nYear) < 6)
			{
			 alert('Invalid expiration year');
			 expires.value = "";
			 expires.focus();
			 return false;
			}
		return true;
	}

</script>
</head>
<body>

<form method="post" action="" onsubmit="return validate(this)">
Expiration Date MMYY: <input type='text' name='expDate' size='3'>
<br>
<input type='submit' value="Submit">
</form>

</body>
</html>

thank you very much... but i still have a problem with the code... for example the digits '1304' , the alert only says invalid month, it should be followed by another alert that says invalid year... how can we do that?

Sorry, but if one part is "invalid" the rest of the function is not executed.
