sceneWindow2D.loadlevel not working.

Hi I have been struggling to get iTorque 2D to load a level for a couple of hours now and while I have been able to swap levels using the behaviour genericbutton I would rather try and do this via script as I cant call functions from behaviours.I dont seem to be getting any erros in my console but I do get a black screen.
this is my game.cs


function startButton::onMouseDown(%this, %modifier, %worldPos)
{
if(startButton.clicked)
{
return;
}
else
{
startButton.clicked = true;
schedule(10,0,"loadSectorChoice");
echo("button has been clicked!!");
}
}

function startButton::onMouseUp(%this, %modifier, %worldPos)
{
startButton.clicked = false;
}
//
//
function loadSectorChoice(%level)
{
%level = "/game/data/levels/sectorMenu.t2d";
sceneWindow2D.endLevel();
if (isFile(%level))
{
sceneWindow2D.loadLevel(%level);
}
}
