Issue I need help with

I have something I need help with please.

  1. Used + to enter a new item. All info is filled. But then I want to allow any user to “order” this item and so the info they enter on this new form should fill the remaining cells (not create a new line under with that information, which it’s currently doing.) Unique identifier perhaps or how can you tell it to continue filling remaining cells.

  2. On that exact second form that I described above, I am unable to click submit when there are two OPTIONAL fields. Note + Photo uploader. Those two I have set to optional (required is not checked) but still the form won’t enable submit unless they are filled.

Appreciate your help!
