How to make a price list with checkboxes and total in a form

1. Click “Add field” and select the type “Set of services with prices”.
2. In the “Services and prices” field, enter items, one per line: [label] Name | price | unit.
3. Save. A total will appear below the cards — it recalculates with each check.

Labels at the beginning of a line:

• [!] — always included, cannot be unchecked;
• [x] — checked by default, [ ] — unchecked;
• [1], [0] — quantity with “−/+” buttons, starting from 1 or 0 (e.g., months of support).

The line # Heading starts a new group, the line > text — a description of the item above it.

If items have units like “mo.” or “yr.”, a line “Next: …” will appear below the total — how much you'll have to pay each period after the first payment.

Names, descriptions, and prices can be edited directly on the page: click on the text, Enter — save, Esc — cancel. New items, order, and labels can only be changed in the field settings.

The amount is calculated by the server based on the field settings, not the browser, so the visitor cannot tamper with it. A form with such a field records each submission as an order, and “Order composition” and “Amount” are sent in the email. To open payment immediately after submission, add the Pay rule to the button.

If it didn't work

• “Service list is empty”. There isn't a single item with a label in square brackets in the lines. Check that each item starts with [ ], [x], [!], or a number in brackets.
• Strange “per service” next to the price. The unit is inserted after the word “per”, so write it in the correct form: “service”, “session”, “mo.”.
• Need to choose exactly one plan. There are no such labels. Make plans items with quantity [0] or move the choice to a separate “Radio buttons” field.
