I've created a repeating table to create an bill of materials.
I have an expression box as the last field in each row that calculates the product of "Quantity" and "List Price" to give "line item total".

I now want another expression box in this and another view that evaluates the sub of all the "line item total" fields to produce a total order value.

Can someone advise on the expression I should use here please?

Hi Taffman and welcome to the forum!

This has been discussed many times here on the forum. There is a search box in the upper right corner of the page that would be helpful, but here's a link to start:
