Unlock movement input

I want to be able to move around my scene using mouse and touch inputs. The blueprint for the touch and mouse inputs has been set up. The issue is that when I go into play mode the inputs don’t seem to work? When I use the mouse scroll wheel nothing happens. It seems as if the movement input is locked.

Is it just a case of the mouse not being captured? Sometimes you need to click the screen to get it to respond when playing in editor.

I have tried clicking the screen but have had no luck in solving the issue. Clicking the screen doesn’t seem to solve the issue.
