New to Lime. and Tiled

Hi I have tried to get Lime working and have done the first exercise
but when the I run it. All I get is a black screen. No errors ! What am I
doing !!! I have a feeling that it may be in the way I am saving the tmx file, which seems to be different now.

CODE:

display.setStatusBar( display.HiddenStatusBar )

lime = require(“lime.lime”)

local map1 = lime.loadMap(“try4.tmx”)

local visual = lime.createVisual(map1)
