I've been running a particular Fabrik form in J3 for some years without issue, it's a simple sale entry with the sale detail - customer, order date etc in the main List/Form (t_sales) and the items ordered in a joined repeatable List (t_sale_items). The first screen print illustrates how it looks with some Calc fields settin the net price/unit and line totals I tried updating this to J4.3.1 F4G3 and had so many problems I decided to start from scratch but have run into a similar problem in the new build. Below you can see that the new build calculates fine in the first line of the repeat group but then fails - in fact it just takes the value from line 1 irrespective of the changed detail in subsequent lines. Further, as can be seen, it switches the first Yes/No field without input from the user. I'm seeing no warning or errors in the Consol or Network, etc. Any ideas please?
