There are a few things wrong with Tickets_progress EventGraph. You need to call SET \Ticketss from somewhere as currently it is not running. So you could attach it to Event Tick which is not the most efficient way or you could use a timer. Also you want the max value in the Clamp to be 1 as the Progress Bar value is between 0 and 1. Here is it attached to Event Tick; you can try the timer afterward if you get it working. Also make sure you have a level named MainMenu created.
