I'm having a problem with NDSolve. See attached picture. I have a package generating a set of ODE's, which I display, and then the next line is the NDSolve integration. I get an "Encountered non-numerical value for a derivative at t==0" error, and I can't spot the mistake. The one thing that looks suspicious to me is the terms in the Equations of Motion that look like "0.05.2". It looks like it should be "0.05*2", but I don't understand why it doesn't just evaluate it.

Best Wishes
-John
