How to perform some dynamic calculation for Configurable List?

Hi, may I know is there a way to retreat the number of rows so that I can perform some dynamic calculation on the fly?

Thank you!

Unfortunately, it is not possible to perform calculations based on Configurable List widget. If you need to have sets of fields on the form and include answers in calculations, you may consider re-creating sets of fields under multiple Section Collapse elements and show every next section conditionally.

We will be glad to assist if you need more help, just let us know.
