Hi good morning

I have Odoo17 enterprise online subscription.

- I know the procedure for inserting a new field in the extra checkout step.

When the customer buys online as a guest I have to collect a code to make an invoice.

1) I use the standard field for message on order

2) I added new text field

3) the customer enters the code in the second field

4) the code must appear in the customer's card ("contacts" app)

5) the code must appear in the sales quote.

I can't do steps 4 and 5

Can you help me thanks

Roby
