What do you return from the onsubmit? If the onsubmit code evaluates to
true then the form will be submitted causing the page source to change
which would cause unpredictable results for the AJAX response depending
on several race conditions. Can I suggest you let us see the whole form
so we can see exactly what the onsubmit code does.
