Do you have the x and y values plugged in? Like I noted my game is top down so I don’t use them, depending on your game you may need them. Screens of your BP and what’s happening in game would help to understand what exactly your trying to make happen, also make sure any objects, terrain, actors ect … That’s need to be aimed at, have the visibility (or whatever channel your using for the mouse hit) set to block and have collision setup properly
