Question: Undefined

While using Maple 10 at school I ran into an error when trying to plot a spacecurve within a 3D plot. When I enter: > A:=spacecurve([2*x,0,0],t=0..1); I get: A := PLOT3D(CURVES([[undefined,undefined,undefined],[undefined,undefined,undefined].. That take up half the screen. If I try to plot this, there is no curve on the plot, but I can see the axes. WinXP SP2 1024Mb RAM (I think) Nvidia Ti-4200
