Modify cylinder to modified curve


this is what I have to do: I have a curve, which I modified (with the curve modifier) to another curve. Then I added a cylinder. Now this cylinder should follow exactly the course of the modified curve. So I applied the curve modifier to this cylinder and selected the curve. Now the problem is, that the cylinder follows the usual curve, not the modified curve.

Does anybody know how I can solve this problem? Maybe if I could create a new curve, that is exactly as the modified curve, but hasn’t been modified, I could solve the problem.

Kind regards,

Did you apply the second curve modifier to the first curve?
