[jQuery] Form submit issues

[ChrisR]

What is wrong with this code?

<code>$(document).ready(function() {
        $("#f_submit").hide();
        $("#f_altsubmit").click(function(event) {
                $("#checkoutform")[0].submit();
                return false;
        });
});</code>

In FF3 this throws an error in the Error console : Error: $("form")
[0].submit is not a function
but this error does not show up in Firebug.

Also what is strange is that when i change the method from submit() to
reset() ... the reset works ...
It seems my form doesn't have the submit method in FF3????
