i am trying to do a poincare map. i generate x[t] and x'[t]. i write z2 = Table[Evaluate[{x[t] , x'[t]} /. %], {t, 0, 10, .005}] ListPlot[z2] and i get a set of values that looks like {{0.517671, 9.75893}}, {{0.562696, 8.33465}}, {{0.601599, 7.26733}}, {{0.635675, 6.38612}},.... the problem is when i use ListPlot[z2] i get the dreaded "is not a list of numbers" error. if i remove the extra parenthesis by hand it works, but thats a tedious business several hundred points. i am sure this is a simple thing to fix. i would appreciate any help. mario
