All,

I have a question that looks fairly trivial, but I cannot solve it....
Please help!

Thanks, JM

Here is a simplified toy example.
When I type
Plot[{a x /. {a -> 1}, a x^2 /. {a -> 1}, a x^3 /. {a -> 1}}, {x, 0,
  2}, PlotStyle -> {Red, Green, Blue}]
I get 3 curves with different colors.

Well, when I type
Plot[{a x, a x^2, a x^3} /. {a -> 1}, {x, 0, 2},
 PlotStyle -> {Red, Green, Blue}]
I get 3 curves but they are all blue, WHY?

However, when I evaluate {a x /. {a -> 1}, a x^2 /. {a -> 1}, a x^3 /.
{a -> 1} and {a x, a x^2, a x^3} /. {a -> 1}, they both give the same
result....{x, x^2, x^3}.

Thank you for your help!!!
