I'd like to clarify or make this question simpler: M0=NDSolve[{a'[s]==U[a[s]],a[0]==X},a,{s,0,6},Method->"ExplicitRungeKutta"] Where X = {1,0,0} and U = {f(x,y,z),g(x,y,z),h(x,y,z)} That does not work and I can't figure out why. The error I get is "Part::partw: Part 2 of a[s] does not exist." Same with "Part 3". -John
