Tiled map not being drawn

[NoxBrutalis]

Hi, Im new to phaser, and am trying to use a tiled tile map. I tried various ways myself, without any joy, so I decided to copy paste one of the examples from phaser3, - the tilemap example : http://labs.phaser.io/view.html?src=src\game objects\tilemap\static\tiled-json-map.js

the example works online, but when i alter it to use my assets, it doesn't draw anything! 
here's the code I'm using:

var config = {
    type: Phaser.AUTO,
    width: 800,
    height: 600,
    backgroundColor: '#2d2d2d',
    parent: 'phaser-example',
    pixelArt: true,
    scene: {
        preload: preload,
        create: create,
        update: update
    }
};

var game = new Phaser.Game(config);
var controls;

function preload ()
{
    this.load.image('tiles', 'assets/tiles.png');
    this.load.tilemapTiledJSON('map', 'assets/tiledMap.json');
}

function create ()
{
    var map = this.make.tilemap({ key: 'map' });

    // The first parameter is the name of the tileset in Tiled and the second parameter is the key
    // of the tileset image used when loading the file in preload.
    var tiles = map.addTilesetImage('tileSheet', 'tiles');

    // You can load a layer from the map using the layer name from Tiled, or by using the layer
    // index (0 in this case).
    var layer1 = map.createStaticLayer('floor', tiles, 0, 0);
    var layer2 = map.createStaticLayer('walls', tiles, 0, 0);

    this.cameras.main.setBounds(0, 0, map.widthInPixels, map.heightInPixels);

    var cursors = this.input.keyboard.createCursorKeys();
    var controlConfig = {
        camera: this.cameras.main,
        left: cursors.left,
        right: cursors.right,
        up: cursors.up,
        down: cursors.down,
        speed: 0.5
    };
    controls = new Phaser.Cameras.Controls.FixedKeyControl(controlConfig);

    var help = this.add.text(16, 16, 'Arrow keys to scroll', {
        fontSize: '18px',
        padding: { x: 10, y: 5 },
        backgroundColor: '#000000',
        fill: '#ffffff'
    });
    help.setScrollFactor(0);
}

function update (time, delta)
{
    controls.update(delta);
}

 

and here's a link to the tilemap and the tilesheet.

The example game runs without any errors, but doesn't show the image.
Thanks a lot for your time.

Update/Answer:

Sick of being stuck, I decided to mess around with an image, weighing up the idea of just using a big image instead of a Tmap, as I was experimenting, and using the scrolling screen code in the above copied demo, I found the structure from my map, it simply wasn't on the screen, and because the map was empty except for a building off-centre, it looked empty (no way to even tell that the scene was truly scrolling).

So, sorry to anyone who may have looked at this - stupid mistake ?
