Tile Layer Loading Problems

Hey folks.

When I create a tile map with two layers, I cannot seem to get my code to read it. Actually, when I load up my code, it says a Datablock is invalid, but when I have only the single layer tile map, there is no problem. Also, T2D doesn't seem to be able to read the dual layered map.

Now, the first tile layer is normal while the second layer has colisions, so could that be my problem? Here are snipits of my code:

// Create images for the tilemap
datablock fxImageMapDatablock2D(levelMap)
{
mode = full;
textureName = "~/client/images/Fake_bg.jpg";
};

// Create images for the tilemap
datablock fxImageMapDatablock2D(Fake_bg_ground)
{
mode = full;
textureName = "~/client/images/Fake_bg_ground.png";
};



// Creates a tile-map
function CreateTileMap()
{
// load tile map
%levelMap = new fxTileMap2D() { scenegraph = t2dSceneGraph; };

// load saved tile-map file
%levelMap.loadTileMap("~/client/maps/Fake_bg.map");

// load tile layer from tile-map
%LevelLayer = %levelMap.getTileLayer(0);

// Sets position of LevelLayer
%LevelLayer.setPosition("0, 0");

%LevelLayer.setTileSize( "100, 75" );
%LevelLayer.setWrap( true, false );
}


Am I just being ignorant on something? :) Help please!
