Hi Nikihl,
"eqs /. %" gives you a list of functions. To pick one, e.g. the first
one, use Part: (eqs /. %)[[1]].
Step by Step results can be obtained using EvaluationMonitor, see there.
hope this helps, Daniel

I am happy with the results, but I don't know how to plot a single function, of the eleven that are solved simultaneously.
