That worked perfectly, thank you. I have another question now.
I set up the invoice so the price for each item is on the right which is a product of the quantity and price in the same row. Is there a way to make enter or tab insert another line with the same formula as the line above? This way more items can easily be added to the list while retaining the formula.
Also, I set the description column to wrap text, but only the first line shows up in the main window. When I edit it through the top entry, it shows all the lines. How do I get them to show up when printing? I tried setting it to auto-height in the hopes it'd adjust the row to the height of the cell, but nothing happens.
