[jQuery] jQuery Form Processing

[jQuery] jQuery Form Processing

Hello,
I'm trying to use this method to process a form and return an alert
without navigating to a new page for the form processing.
http://jquery.malsup.com/form/#getting-started
I have this in my <head> statement:
<script type="text/javascript" src="js/jquery-1.3.2.js"></script>
<script type="text/javascript" src="js/jquery.form.js"></script>
<script type="text/javascript">
    $
document
.ready
function
{
        $
'#autoSumForm'
.ajaxForm
function
{
            alert
"Thank you for your comment!"
;
        }
;
    }
;
</script>
And this is the form:
<form name="autoSumForm" action="posttime.php" method="post">
...
<input type="submit" name="submit" id="submit" value="Submit" />
</form>
When I click the submit button though, it takes me to posttime.php,
and doesn't give the alert.
What did I do wrong?
