How to use touch to spin an object around?

Hey everyone, a friend and I are making a game and I’ve been working on the blueprints. I am still learning Unreal 4 and been trying to figure out a solution to this problem. We need a disc like object follow your finger movement and it will spin in the direction you are spinning your finger. It would be like putting your finger on a record then spinning it around. I want the disc to spin as fast as you are moving your finger. Here’s a screenshot of what I have so far. It’s KINDA doing what I want but It needs to go around in full circles as your finger does. I know the input touch state with location x added to rotation is wrong. I don’t know how to get the position of where you touched the object so that it rotates to that point. Anyone have any ideas on where to begin? Thanks.
