Is it possible to have an upload form in a form?

I inserted uploadforms in my admin editpage.

A user can upload a pic for each day of a trip. (it's also posssible to edit the content in the same section)

There are multiple days on the page.

After I insterted the uploadforms I noticed that my main form doesn't work anymore.
Isn't it at all possible to have uploadforms embedded in a form?

I can solve it by moving the uploadforms below my main editform, but I would like to have the uploadform for day 1 next to the content of day 1 and so on.

Is there a solution ?
