I understand how to make text boxes, buttons, checklists, etc. for an interactive form in indesign, but is it possible to make a calculating form?
I'm trying to create an order form, which I've gotten to work pretty well in Acrobat, but it's a huge pain to edit in Acrobat. Is there a way to do this all in Indesign? What I'm wanting to happen is to have a table with 3 cells. A1 would be a user submitted number, A2 would be a fixed price, and A3 would be the total. The way I am thinking about this working would be to have A1 as a text box, A2 as a read only text box, and A3 would be the formula of A1*A2. Then at the bottom of the form, I'd have E3 be A3+B3+C3+D3.
Does this make sense? Is this possible?
To create a form with calculations, while you may start it in InDesign, you'll have to set those options in Acrobat Pro.

I recently discovered this (plugin (.js) for table calculations in InDesign:
