Using your tutorials as a guied which by the way are fantastic, I also included a "discount percent" field. Everything works just like I want it to work thanks to you. However, if I go back to look at an order say a month ago it shows me the info which includes the discount amount as well. If I change the discount amount to another amount it reflects on the older invoices as well. Is there a way so that when something changes say discount or tax amount that it doesn't interfere with something in the past? Would very much like to hear your thoughts on this
Thanks Rich
