Hello,
I’ve got something similar and it works except for one problem.
It seems there is an issue with using type = file in the multiple fieldsets. If you hit Add New, it seems to copy (in this case) the image to the new item you are creating. It shows a thumbnail with the delete checkbox next to it. If you hit browse and select another file then update, it deletes the image on the fieldset above.
It only seems to happen to the type= file field, all text is fine.
proximity2008, do you have any ideas?
