Password Problem

I'm a noob when it comes to web dev but here it goes.
I have an assignment due soon and im having some trouble.
im required to design a program that will only grant access to the web page when the correct pin is entered. the pin is any number between 1000 - 4000 inclusive. there is also a max number of incorrect attempts(3 by default) which is to be implemented by a loop.
This is what I've got so far, help anyone?

<Title>Login Page</Title>
<head><link rel="stylesheet" type="text/css" href="stylesheet.css">
<script type="text/javascript">
function CheckPin(password)
{
var att = 1;
while (att <= 3)
{
if(password < 1000 || password > 4000)
{
alert("Incorrect Password");
att++;
return " ";
}
else
{
window.location = "index.html";
}
}
}
</script>
</head>
<body>
<center><img src="images/pic.png"/><br/><br/>
<p>This is a password protected site.<br>
<form name="password" action="index.html" method="get">
Password:
<input type="password" name="password" size="4">
<input type="button" value="Login>>" onclick="CheckPin('password')">
</center>
</form>
</body>
</html>

Have a look at your OnClick call. You're passing a value of "password" rather than the value that has been typed into the password field.

Thanks I understand.
But how do I pass the entered value as an argument??

Google is damn helpful with coding.

I know it depends on the level of the course, but bear in mind that JavaScript wouldn't be appropriate for this (unless that's what the assignment was).

One quick "view source" and someone would see what passwords would work.
