I have created a form that has fields that I made required. I want to create a popup message when the required fields are not filled in. Can someone please show me how to do this or direct me in the right direction. Thanks.

This is what I found so far but I'm not sure how to do this with multiple fields.
Example:
<html>
<head>
<script type="text/javascript">
function validate_required(field,alerttxt)
{
with (field)
{
if (value==null||value=="")
{
alert(alerttxt);return false;
}
else
{
return true;
}
}
}
function validate_form(thisform)
{
with (thisform)
{
if (validate_required(email,"Email must be filled out!")==false)
{email.focus();return false;}
}
}
</script>
</head>
<body>
<form action="submit.htm" onsubmit="return validate_form(this)" method="post">
Email: <input type="text" name="email" size="30">
<input type="submit" value="Submit">
</form>
</body>
</html>
