I'm a bit new to Zoho Creator and I'm trying to create a form that allows a user to order materials

-I'd like the user to be able to add a material, the price, and some other fields in one section.

-Then, I'd like them to be able to add another section with the same fields for the next material needed to be ordered.

-After they're done, I'd like the form to be able to calculate the total price

-I'd like the form to be submitted for approval.

-I'd like the approved form to be stored in the CRM. 

How much of this is wishful thinking?
