Null object when using createwindow

When im using create window, I want to have a windowed mode with my game that either uses glmax2d in fullscreen or maxgui with a canvas in windowed mode but when it reaches the create window command it pipes up with an error telling me im trying to access a null object.

All im doing is:

Framework brl.glmax2d
Import brl.maxgui

Global GameWin = CreateWindow( "TileCascade - Copyright ©EdzUp", 0, 0, 640, 480, 0, 15 )
Global GameCanvas = CreateCanvas( 0, 0, 640, 480, GameWin )

Repeat;Until MouseDown(1)=True
End

is there something im missing as its driving me nutts.

Framework BRL.Win32MaxGUI
Import brl.glmax2d

Global GameWin:TGadget = CreateWindow( "TileCascade - Copyright EdzUp", 0, 0, 640, 480)
Global GameCanvas:TGadget = CreateCanvas( 0, 0, 640, 480, GameWin )

Repeat

Until MouseDown(1)=True
End

thanks will have a look :D

finally I just added:

Import brl.Win32maxGUI
import brl.glmax2d

I added this to the import of the source and it works perfectly :)

yep, you might want to check out the Framework Assistant

yeah got the framework assistant, but it wouldnt work on TileCascade something about cyclic errors although the game compiles perfectly in Max.
