As I was trying to rush to a meeting with a client yesterday, I looked at their invoice and saw that I forgot to add in a 10% discount on the total order as I had promised.
So I create a subtotal item at the end of all the items in the invoice, which for example gave me a subtotal of $500. I wanted to apply the 10% discount, so I made a discount item and applied it right below the subtotal with the amount of "-10.00" in the price field as instructed in the help files... all this had done was subtract $10 bringing the total to $490 instead of $450... Any reason as to why it didn't work?
Thank you for your help.
