Return Value Runtime Error
Hi everyone. I finally got a problem fixed but now ran into another problem. I have a widget button cast to the level bp with an event dispatcher. Ever time I click on the button everything plays just fine but when exit out I get a runtime error. However for some reason when I use a event begin play, it works with no problem! Can any please explain whats happening. Here are some screen shots.

I think the problem is that you attach your "bind event" to tick function. it will attempt to make a new binding on every tick. which is totally wrong :)
you can simply bind your event ( and should ) once and they will work until you unbind them.
the issue is that the value you are using for the binding is coming from another flow and it might not exist.
