Exclude Gift Certificates from sales totals

When I was configuring it first I used it as that’s what prints on the receipt. I Tried changing it but it wont update.

I had a similar error a while back with {REPORT TICKET DETAILS:TXT.23% Vat} that emre fixed after reviewing a database copy.

If you look at his post on that topic emre is using %8 Tax and %18 Tax and they work fine. It may have to do with the placement of the symbol.

Have you any experience editing transactions. I need to get a report for tax return for accountant and I am trying to correct errors by modifying the transaction documents but I cannot seem to get ticket or report data to refresh with the new data.
I have tried editing inside sambapos and also directly in the database. When I navigate to accounts all the information has been updated.
