Animation Frustration

I'm trying to load animation from .3ds and .x files by following the Help text, but the meshes are frozen. Is there a trick to getting them to animate? Here is the code:

Graphics3D 640,480
SetBuffer BackBuffer()
camera=CreateCamera()
PositionEntity camera,0,1,0
light=CreateLight()
RotateEntity light,90,0,0

Global Hero = LoadAnimMesh("media/Babe-Idle.3DS")
LoadAnimSeq(Hero, "media/Babe-Move.3DS")
attack = LoadAnimSeq(Hero, "media/Babe-Attack.3DS")
PositionEntity Hero,0,0,15
Animate Hero,1,1.0,attack

While Not KeyDown(1)
UpdateWorld
RenderWorld
Text 0,10,"Animation " + Animating(Hero) + " Sequence: " + AnimSeq(Hero)
Flip
Wend

The output claims that the character is animating, on sequence 2, but no motion is visible. I know that the animation in the file does function and I have seen it work under Blitz3d, but this simple example fails.

Can anyone help? Thanks.

don't use attack this way, instead simply say

loadanimseq(...

without an asignement and then use the sequence INDEX with the Animate command:

animate hero,1,1.0,2

or
attack=2
animate hero,1,1.0,attack
