In the blueprint for thirdpersoncharacter there is a skeletal mrsh of the ue4 guy called “mesh”, honestly it can be called what ever you want but its referring to the skeletal mesh that has the money socket. When you attach it to an actor and say attach to socket money, it has no idea what is socket money. So you have to reference the skeletal mesh called “mesh” because thats where the socket money is held. So if you make a variable, call it whatever but the type of the variable, I used thirdperson character reference. So immediately it grabs the thirdpersoncharacter blueprint and out of that I pull a string, type “get mesh” because inside that blueprint it has a “mesh” thats a skeletal mesh of the ue4 gray dude. Now that im thinking about it. Im using the third person template. When you started your project, did you use a template or standard blank code?? Plus here might help, send a screenshot of your player character that you control. But the viewport one like I did in my first picture. But instead of the money bp take it of the player you control. You may not have a mesh name in there and that maybe why you cant get it. But if you take a screen of your playable character I can tell you which one to grab instead of mesh because you may have a different name
