Unable to make roll curve joint mechanism

Please see the attached image.
I want roll the cylinder about the block. I have applied slide curve joint and roll curve joint.
When I want to simulate it. A message occur: This mechanism can not be simulated.
Please suggest, What type of error I do?
Thanks in advance.
Accepted answer

1. If you want the rod to roll about the block, why did you add the sliding joint? Delete the sliding joint
2. Make sure you define the Rolling Curve joint with an input command. The error message says you need a command.
3. I see an error in the tree with the offset constraint. The two curves that are rolling on each other should be co-planar.
