Make array follow path or curve? Not working.

I create an array of cylinders for example, and pick Fit Curve.

I can then select either a Bezier Curve, or a Path. I can get the length of the array to change but its path never conforms to the curve or path.

What am I missing?

Thanks

Put a curve modifier after the array and tell it to use the same curve.

Perfect - thanks so much.
