*shrugs* up to you, brian means to use string.splice(a); where a = number of characters before the index that is tacked on. so if the name/id is foo_1, foo_2 then you'll do:
$('[id^=foo_]').change(function() { $('[name=post-amount_' + $(this).attr('id').slice(3) + ]').val($ (this).val()); }); I personally find this kind of string munging difficult to read and maintain. Could just be personal preference though. Good luck. Josh Powell On Mar 10, 10:39 pm, Eric Gun <gunawan.e...@gmail.com> wrote: > @mkmanning: Well done!! Your script works well.
