I have a repeating group of items to purchase.
Each item has, among other fields: price, tax%, quantity.
Because I am using auto binding I don’t want to create field for each item that calculate Tot Netto and Tot Brutto for each Item (I would not know how to auto-bind them!).
Therefore I want to have a Text fiedl in the bottom that Calculates the totals of all the item in my list:
TOT NETTO: for each item. multiply price/unit and quantity and summ all of them
TOT BRUTTO: … add taxes.
Any idea how to do it?
