Especially Section 1.7 and 1.9. You should use C1[X,Y,Z] in the plot statement instead of just C1. Also, then you don't have to make an assignment to Z. Here is a simpler way to do what you wish: f[x_, y_, z_] := x y^2 z^2 Plot3D[f[x, y, 0.5], {x, 0, 10}, {y, 0, 10}]; David Park djmp at earthlink.net http://home.earthlink.net/~djmp/
