Hi Max,
Its working fine for me ,
You can use debugger to get the root cause, however in your case if you perform this activity . You need to log as Event manager and configure Festival days . Then create an Event and it will work, as per the debugger screen shot it says that Visitor list is empty and thus giving you the error.
[EventManagement.Visitor_Ticket/EventManagement.Ticket/EventManagement.Ticket_Day = $IteratorDay]
Hi Max
Thank you for your screenshots, they were really helpful.
The error states that your $Count variable is empty. So I suggest to put the debugger on your variable and see what happens with it.
I hope this helps.
Kind regards,
Leander
