You want to create a float (not an int) in both your FX layer and your expression parameters, just like you'd create an int for a toggle. In your expression menu, you create a radial puppet, and set the parameter it adjusted to the float you created. In the animation state in your FX layer where you put the animation, you check the Normalized time checkbox and set the parameter to the same float. Now your radial puppet will go from 0-100, and that will scrub through the animation from the first to last frame.
