Stage Not showing

I have tried the plugin but cannot get the stage picture to show? What am I doing wrong.

Also, do you ever have any voucher codes for your add-on as I want to purchase the “Booking Cancellation” “Special Price” and “Printable Reports” but that works out quite expensive for simple functions that most people will need for this type of booking system.
