Need help with ODEsolve

I'm having trouble using ODEsolve in MC14. I've gone through the examples, and they work fine. But the first problem I tried for real, doesn't work.

The solve block has only two lines, and only the first derivative of one variable. But I'm getting the dread "This variable is undefined" error.

I'm attaching the file. Any help would be appreciated.

By the way, I've selected the adaptive solver.

If you really want v'(M) to be dependent on f(v) you have to write it as f(v(M)).
