Casting to another BP

Hello, i have this casting set up, however, it always fails.

Can you find what´s wrong?

the object you casting is invalid

How should i refer the BP actor i am casting to?

i can’t tell , i need to know the situation ,

Well, i have UMG where you input 7 in 7 SpinBoxes, and i need to set those numbers to variables in “stargate” blueprint.
