Calculate total, generate a URL, etc.

We understand the challenges that come with lengthy forms, and that’s why we’ve have the “Save and Continue” feature. Say goodbye to the frustration of losing progress or rushing through extensive forms in one go. With this must-have feature, you’re in control of your time and information. This feature also allows users to save their progress automatically in Airtable so they can pause and resume without worrying about data loss. You can also require user confirmation before the final form submission.

Moreover, this allows you to handle computed fields within your miniExtensions form. For example, show a calculated price total or generate a URL. Let your employees/customers see their input results immediately.

Here is a form that has a formula field to show the order’s total.

The secondary line item form has calculation mode on, but the calculation it shows on the form is based on a rollup value from the main record. When the form is submitted, the calculation works well. But when calculated before submission, it behaves as if it was not linked to the main record. Is this the normal expected behavior?

I switched on the Computed field which contains a formula from Airtable. But a new record gets created when it is only computed in the form. Before I see the success message.
