    Hm... can anyone help med how I can limit a form input to not be more than a specific value? For instance you should not be allowed to type in a number more than 1826. Is this possible to do in some way? Please help!

    Thank you for your support

    Try this...

    
<html>
<head>
<script type="text/javascript">
function limit(element, num) {
	if (element.value>=num)	element.value = num;
}
</script>
</head>
<body>
<input type="text" name="someNumber" maxlength="4" onkeydown="limit(this, 1826)" onblur="limit(this, 1826)" />
</body>
</html>
    HTML:
    Hope that helps somehow. :)
