Need Help with Launching My Character

I’m a beginner and I’m learning how to launch my character with the BlueSprint, from this tutorial

I cannot make it. I didn’t follow the exactly step as this tutorial since the version is different. Here are my steps:

Create empty Actor Bluesprint class → make a cube as a component → set it in the scene as the LacunPad → make the Bluesprint as the attached image.

Please tell me why it does not work and help me to correct anything I did wrong.

Thanks a lot!
