Can you screenshot whats in the left of the blueprint where it shows a list of your scene and what childrens you have in the scene.
Thinking about this I see its done in the money blueprint. I usually do mine in the blueprint that is going to be attached to. So all in all since this isnt in the character blueprint you need to access your character bp to get the mesh of your character. The socket name you used is money indicator. Where is this socket located?? And it has to be correct spelling so does the socket also contain a space between money and indicator?
