How do i rotate a camera attatched to spring arm?

[link text][1]

I tried creating something that gets swipe and tap input, but something seems to be wrong with the gate or the input itself, because it does not display. I use the values that are retrieved from how far someone swipes to rotate the camera as it swipes. I have created the camera in a pawn class and use it to orbit around a cube i have made from multiple tiles. i just want to be able to orbit around the cube. the tiles used in the cube are multiple instances of a class where a have created a hexagon. I never really had a problem with the swipe when i had 4.11.
I posted a google doc with all my code in the link.
