Rotating a parental entity

Hi,

cannot seem to rotate a parental entity. When I do I get memory access violation. Any thoughts...

Graphics3D 800,600,32,2

; Setup the apps title and close app caption
AppTitle "CuBE v0.01", "Are you sure?"

;Create a parent cube...
parent_cube = CreateCube
;HideEntity parent_cube

; Set the randomizer seed for more true random numbers
SeedRnd (MilliSecs())


Type cube
Field entity
Field x#
Field y#
Field z#
End Type

;Global alien=LoadMesh("alien.b3d")

;Make 50 objects
For i=1 To 10
cube.cube = New cube
cube\entity=CreateCube(parent_cube)
ScaleEntity cube\entity, 0.5, 0.5, 0.5
EntityColor cube\entity, Rand(50, 255), Rand(50, 255), Rand(50, 255)
cube\x#=i
cube\y#=0
cube\z#=0
PositionEntity cube\entity,cube\x#,cube\y#,cube\z#
Next


camera = CreateCamera()
light = CreateLight()

PositionEntity camera,0,0,-20
PositionEntity light,-5,-5,0

While Not KeyDown(1) ; Until we press ESC

If KeyDown(200) Then
RotateEntity parent_cube, 10,10,10
EndIf

RenderWorld ; Draw the Scene
Flip
Wend;

Change

parent_cube = CreateCube

to

parent_cube = CreateCube()

AHA! Oops silly me, thanks. Thats wot happens when code cut code at 3 in the morning!
