Need help with message log

Hello everyone, this week I started using unreal engine (which is really great even if you don’t know much about it) and this is my first post here so forgive me if I don’t know the right ways. I have the following message in my logs: “accessed none trying to read property CallFunc_GetPlayerController_ReturnValue”. I’m really lost, I wanted to make a menu for a little game that I took from a youtube channel and in the video everything worked fine and I did exactly the same things it said. I enclose my code which is wrong. Can you help me? My Best Regards Alex.

Try plugging the controller into the ‘create widget’ node.
