Can values in the configurable widget be calculated?

Using the Configurable List Widget. Is it possible to calculate values from this widget and return into another field?

In my example, I would like multiple invoice amounts to be totaled and entered into the Total Invoice field.

Unfortunately, it is not possible to perform calculations with the values in the Configurable widget. If you need to perform calculations, you may add the normal fields to the form and use calculation widget to perform calculations. Please refer to the guide below that can help you with performing calculations.
