How to let customers add as many items as they want (rooms, products, properties)

Step by step

1. Name the repeating thing

   "Customers can add several rooms. For each room I need length, width, and floor type."

2. Say how each one is priced

   "Each room costs area times the rate for its floor type." The form works that out per room.

3. Say what to total

   "Show the customer the total across all rooms." You can also show only the grand total and not the per-room figures.

4. Set limits if you want

   "At least one room, at most 12."

The words to say

Copy this into ChatGPT (with CalcForms added) and fill in the brackets.

What you will see

A small block per item with an "Add another" button; a running total that updates as they add or remove items. Every item comes through in the reply.

Common mistakes

• Putting too many questions in each item. Three or four per item keeps it quick.
• Forgetting a maximum. Twelve rooms is reasonable; two hundred is a spreadsheet, not a form.
