It’s not enough to have a variable of the correct type, it actually has to be assigned to something:
or
It can’t be. How does it know which pay wall object to choose. Theoretically, you could have hundreds… 
Id really appreciate your help on this, (Yes Ive tried google)
I make something super simple.
- A Text Button Widget.
- I create a widgetInteratction component on my character
- Pressing the button works it prints hurray!
- Now things go wrong.
- I have a Payment wall blueprint, meaning the character has to pay coins to open a gate. but i just cant call that function.
- I try to call the function from the button. but it just gives me the error in the image, that it returns empty.
The help on the error log in this engine is very very very very limited, so I am dead in the water. Any help would be deeply appreciated.
Thank you.
So I need to set the variable first? I thought it was automatically set when I create the variable and set variable type to PayWall?
That was my plan! Thank you it works with this!
My plan is to make walls that demand payment, the idea is to make one wall blueprint that just has a variable the Game Designer can change up and down.
I really appreciate your help.
Last question for tonight!
I am trying to set the price of the wall. This has to be a variable that is unique to each wall so I need to set the variable pr wall. How do I create a reference from each wall to the widget UI bp?
This doesnt seem to work then?

Assuming the wall triggers the widget appearance, when you add it to the viewport, the wall can ‘reach inside’ the widget and set the wall variable.
