Go to Show | Edit a show and click the Run of show prices button.
This is the Run of show prices window. To add a price code, click on the Add a price button.
NOTE: Whatever is input into Print on tix as column will carry over to the Printed as field when you click on the ellipsis in the Details column.
(This window looks a little different from what you may be used to if you have been using Wintix 5. The way price categories display in Wintix 6 is to accommodate more information in each price category.)
