Best Way to Move the Camera Up & Down Slopes?

Wow i was missing a few things, like using a Flnterp, the delta time and the required height nodes. I went straight off the world location xy to the set vector location and came off the vector distance straight to the z location. This worked thanks for your help.

Now I just have to figure out why when the camera sphere is on a slope and I rotate the camera with its back against the slope the sphere then falls through the ground and gets stuck below the terrain.

Update, its not the rotation, its the pan up/down. When I pan the camera to be more of a level angle with the ground and move it backwards to a slope the sphere falls through the ground. I caught the sphere moving up and down on the Z axis over a flat surface when I pan the camera down closer to the ground.
