Need help with blueprint

My book “Unreal Engine dev in 24 hours” has a try it yourself involving blueprint classes. It’s to create a pickup. I followed the instructions in the book, but when I try to compile it, it gives me an error and it says at the bottom “This blueprint is not a SceneComponent, therefore Target must have a connection”. The book never told me about a connection of any sort. What am I supposed to do to fix this?

It would be a lot easier and quicker if you show us the blueprint.

Okay. Here you go.

It worked! Thanks!
