Camera Zoom. Top Down?

I have made a blueprint to zoom the camera in a thirdperson example project. It uses the mouse wheel to zoom in and out by the spring arm. For some reason I can not figure out how to make the same thing work in the top down example project. Something is stopping the character blueprint from changing the camera controls. Ive been at this for hours plz help.
THANKS!!!

Go to controls and uncheck block input. Should work then.
