Is it possible to perform calculations in the configurable widget? For example a product list: product, quantity, unit value and total value as quantity x unit value.
I hope you're doing well and thanks for reaching out.
Based on my test, it is not possible because the form calculator widget does not have direct access to each column/field created in the configurable list. It only recognizes the widget as a whole.
I suggest that you use the Product List widget for listing out your products as it has features built-in to display the sub-total, total, quantity, etc.
