Echo Javascript Variable

[Nathan]

The following code I'm having some issues with.  I need to echo the variable "qtycheck" to see if it's getting populated correct as I suspect that's the issue.

How can I echo it out on the page to see?

<script type="text/javascript">
    function check() {
        var elements = document.getElementsByName("quantity");
        var qtycheck = document.getElementById("qtycheck").value;
        for (var i=0; i<elements.length; i++) {
            var nmbr = elements[i].value;
            if (nmbr > <?php echo $maxqtyorder; ?>){
                alert("You've selected more treats than your package allows.");
                return false;
            }
            else if (nmbr > qtycheck){
                alert("You've selected more treats than your package allows.");
                return false;
            }
        }
        return true;
    }
</script>

Figured out by popping it into a dialog box.

 

alert(qtycheck);

The issue was the variable was not being populated, easy to see once I had it to see.
