Mouse Wheel Up/Down don't work

Hi !

This is my controller that I have set by default in my GameMode.

Just a simple event who is activated when we scroll. But it doesn’t work, the string is not displayed …

Why ? How can I fix this ? :confused:

Sure the component is taking correct action. I think I could be the problem. If in Input area of component details Auto Receive Input is set on “Disabled”, try changing it to “Player0”.
