Hi,
Yes, that’s possible. There are two way to do that; displaying the summary directly in the form, before the submission, or displaying the summary in the thank you page (the option with the thank you page is only available in the paid versions of the plugin).
To display the summary in the form you simply should insert a summary field in the form, and select the other fields to include in the summary.
To display the summary in the thank you page is very similar but you should use a shortcode.
Please, check the following questions in the FAQ of the plugin (https://www.ads-software.com/plugins/calculated-fields-form/faq/):
Q: Could be displayed a summary of submitted fields in the thank you page?
Q: Could you show only a subset of submitted fields in the summary inserted in the thank you page?
Q: Is possible formatting the thank you page?
Best regards.
