Scope of Types and Variables?

I'm trying to write my present game as modular and OOP as I can, but I am having a little problem because not all of the Global variables I have made actually seem to be Global in scope. A generic example:

I have my main program:

Import "Map.bmx"
Import "KeyResponse.bmx"

Global BackgroundImage:TImage = LoadAnimImage ( "incbin::resource/tiles.png",CellSize,CellSize,FirstFrame,MaxNumFrames,FILTEREDIMAGE|MASKEDIMAGE)
Global Map:TileMap = TileMap.Create (BackgroundImage,MapSizeRows,MapSizeColumns,CellSize,MapTop,MapLeft)

...etc.

While Not (EndGame=-999) 

Cls
Map.Draw()

'****** Key pressed here, and generates a code to be sent to the keypress function ****
CheckKeys(Map,button)

Flip
FlushMem
Wend

I create my TileMap Type and such in the Map.bmx file, and it works fine...

Type TileMap
	Field HorMapSize = 0, VerMapSize = 0
	Field HorCellSize = 0, VerCellSize = 0
	Field Background:TImage = Null
	Field TopCorner:Float = 0.0, LeftCorner:Float = 0.0
	Field TileType:Int [MaxHorMapCells,MaxVerMapCells]
	Field TopBorder:Float = 0.0, LeftBorder:Float =0.0
	Field PortHorSize = 0, PortVerSize = 0
	
'***************** New ********************
	
	Method New()
		Local x,y
		For x = 0 To MaxHorMapCells-1
			For y = 0 To MaxVerMapCells-1
				TileType[x,y]=EmptyCell
				'Print TileType[x,y]		'Error Checking
			Next
		Next
	End Method

'******************* Create ************************
	
	Function Create:TileMap (TempImage:TImage,TempRows:Int,TempColumns:Int, TempCellSize:Int, TempTop:Float, TempLeft:Float)
		Local TempMap:TileMap = New TileMap
		TempMap.HorMapSize = TempRows
		TempMap.VerMapSize = TempColumns
		TempMap.HorCellSize = TempCellSize
		TempMap.VerCellSize = TempCellSize
		TempMap.Background = TempImage
		TempMap.TopCorner = TempTop
		TempMap.LeftCorner = TempLeft
		
		'Error Checking
		'Print TempMap.HorMapSize
		'Print TempMap.VerMapSize
		'Print TempMap.HorCellSize
		'Print TempMap.VerCellSize
		'Print TempMap.TopCorner
		'Print TempMap.LeftCorner
		
		Return TempMap		
	End Function
	
'******************** LoadCells *************************
	
	Method LoadCells (mapfile:String)
		Local temp:String = Null
		Local x,y
		Local in = ReadStream (mapfile)
			For y = 0 To VerMapSize - 1
			For x = 0 To HorMapSize - 1
				If Not Eof(in)
					temp = ReadLine (in)
					TileType[x,y] = Int(temp) 
				EndIf
				'Print TileType[x,y] 'Error Checking
			Next 
			Next 
		CloseStream in
	
	End Method

'************************ SetWindowSize *********************

	Method SetPortSize (TempLeft:Float,TempTop:Float, TempHor, TempVer)

		TopBorder = TempTop
		LeftBorder = TempLeft
		PortHorSize = TempHor
		PortVerSize = TempVer
		
	End Method

'************************ Draw ***************************
	
	Method Draw()
	
		SetBlend(MASKBLEND|ALPHABLEND)
		SetRotation(0)
		SetAlpha(1)
		SetScale(1,1)
		SetColor(255,255,255)
		Local x,y
		Local ViewX:Int = 0,ViewY:Int = 0,ViewSideLen:Int = 0,ViewDownLen:Int = 0 	'Stores the Viewport size to be restored later
		
		GetViewport(ViewX,ViewY,ViewSideLen,ViewDownLen)
		SetViewport(TopBorder,LeftBorder,PortHorSize,PortVerSize) 'Sets Viewport to visible window

			For y = 0 To VerMapSize - 1
			
				Local YPos:Float = (y+1)*VerCellSize+TopCorner
				If YPos >= TopBorder And (YPos - VerCellSize) <= (TopBorder+PortVerSize)
					 
					For x = 0 To HorMapSize - 1
					Local XPos:Float = (x+1)*HorCellSize+LeftCorner
					If XPos >= TopBorder And (XPos - HorCellSize) <= (LeftBorder+PortHorSize)
						If TileType[x,y]<>EmptyCell
							DrawImage (Background,(XPos - HorCellSize),(YPos - VerCellSize),TileType [x,y])
						EndIf
					EndIf
					Next
				EndIf
			Next

		SetViewport(ViewX,ViewY,ViewSideLen,ViewDownLen) 'Resets Viewport
	
	End Method
	
'************************* MoveMap ***************************

	Method MoveMap(direction_x:Int,direction_y:Int)
	
		LeftCorner:+direction_x
		TopCorner:+direction_y
		If LeftCorner < -(HorMapSize*HorCellSize)+PortHorSize+LeftBorder Then LeftCorner = -(HorMapSize*HorCellSize)+PortHorSize+LeftBorder
		If TopCorner < -(VerMapSize*VerCellSize)+PortVerSize+TopBorder Then TopCorner = -(VerMapSize*VerCellSize)+PortVerSize+TopBorder
		If LeftCorner > (LeftBorder) Then LeftCorner = (LeftBorder)
		If TopCorner > (TopBorder) Then TopCorner = (TopBorder)
	End Method

End Type

My problem comes with Key entry. If I capture a keypress in the main loop, then send it off to the function in my KeyResponse.bmx (below) I get an error that says the type TileMap is not recognized. I thought that since "Map" was a global variable it could be accessed from anywhere in the program, but that seems to only be true from anywhere in the individual .bmx file. Here's the two ways I have tried to code a key response in that file:

If button=1 Then Map.MoveMap (0,-MoveStep) 'This direct call to map doesn't work!

....

Function CheckKeys (TempMap:TileMap, pressed:Int)
   If pressed = 1 Then TempMap.Move Map (0,-MoveStep) 'This doesn't work either!  It says it doesn't understand "TileType"...

Any help understanding the scope of types and variables across Imported .bmx files would be appreciated...

try including rather than importing map.bmx

Thanks! It worked...
