On the Conversion Path report in the Form Engagement section, Exatom reports the total conversion value as well as the missed conversion opportunity.

This value is based on the average conversion value that you can set up on the form setup page. Go to Setup --> Forms and click on the edit icon of the form where you would like to add or change the conversion value. This can be done in the field 'Conversion value (average)' and is a value in Euros.
