Using NDSolve in NonlinearFit

Hi,

I have been trying to use NDSolve inside various Fitting routines
(NonlinearFit, FindFit, ...).  Although the NDSolve works fine both inside
and outside a Module wrapper once inside a "fit"-function the variables are
never resolved.  At least the Print inside the function returns names rather
than numbers??

What is my mistake?
Has anybody solved this problem differently?

I do not wish to write a new Fit-function and search myslef if it can be
avoided.  The text below is copied as CellFormat and can be inserted and
interpreted in any Mathematica Notebook.

Sincerely

       Ernst
