Keyboard Event Not Working

Hey guys,

I need some help since it is been difficult to find an answer to this problem of mine.

I have started less than a month to learn how to use Unreal Engine and the problem bellow appeared in a course I am taking it.

The pictures I attached bring a test to use a Keyboard event and also two exercises from this course. But the problem is that I am not able to make the keyboard event to work when I play.

So I would appreciate some help in this matter.

Some considerations: I am doing this in a level blueprint; on the exercises I am working with actors and the test I made I tried both ways (with and without an act envolve).

Thank you so much for you time and help
