well, you are hooking up to the event that gets fired every time an ajax
request completes.
you "trial" code just replace the fragment with a fixed value, but if you
use ajax instead the ajaxstop will fire in a loop, and it's correct that it
does it.
Why are you hooking up to the ajaxstop event instead of the change event on
the "quantity" field (as per your description on what is supposed to
happen) ?
