Hi,

To do what you need, the easiest way is to flow from surface to surface.
But you could do it from curve to curve, but for this case (curve/curve) you have to do it with the path of the curve, not with the bottom of the text.

In the file I put orange surfaces for surface flowing and Blue curves for Curves flowing.

A small warning, if you want avoid a modification on height of the text you have to modify length of curves.
