How to solve Input Action wrong Action Value?

Hello, thank you very much for the answers.
I am using version 5.5.1.

What you are showing in your reply and the link to the other post is exactly what I saw in the tutorial.
My problem is that despite doing it like this and checking the blocks several times for mistakes I can’t understand why Started returns 0 for me instead of the scalar value.

I feel that I am missing something or a setting is making things not work properly.

Edit:
Same situation here when using the scroll wheel. It does not work if I link to Started, but works just fine if linked to Triggered.

If Triggered works, so should Started right?
