Creo Cam follower coonection not defined

Hello,

I'm in engineering class and I'm currently working on a caterpillar cam toy.

I'm trying to figure out how to define my second cam (the follower) for the mechanism.

When I select my fllower pole surface, it says " please sleect some cam geometry.

I have no problems defining my cam gear (concentric)

I have attached an assembly with my parts.
