Getting error when using buildLayerList function.

Hi,

I am trying to create layer list but it doesn't show when running in the JavaScript. I am not sure what is missing here. Below is the code I am using.

var FiberInfoTemplate = new InfoTemplate();

FiberInfoTemplate.setTitle("Fiber Provider");

var Fiber1InfoTemplate = new InfoTemplate();

Fiber1InfoTemplate.setTitle("Fiber Provider");

var Fiber2InfoTemplate = new InfoTemplate();

Fiber2InfoTemplate.setTitle("Fiber Provider");

FiberInfoTemplate.setContent("PROVIDER: ${PROVIDER} ");

Fiber1InfoTemplate.setContent("PROVIDER: ${PROVIDER} ");

Fiber2InfoTemplate.setContent("PROVIDER: ${PROVIDER} ");

var FiberLayerURL = "https://corp.abc.com/network/rest/services/AMTools/Fiber/MapServer";

var FiberLayerOptions = {

"id": "demographicsLayer",

"opacity": 0.75,

"showAttribution": false

};

var FiberLayer = new ArcGISDynamicMapServiceLayer(FiberLayerURL, FiberLayerOptions);

FiberLayer.setInfoTemplates({

0: { infoTemplate: FiberInfoTemplate },

1: { infoTemplate: Fiber1InfoTemplate },

2: {infoTemplate: Fiber2InfoTemplate}

});

//1 and 5 are the layer id number.

//FiberLayer.setVisibleLayers([0, 1, 2]);

//map.addLayer(FiberLayer);

FiberLayer.on("load", buildLayerList);

map.addLayer(FiberLayer);

function buildLayerList() {

var items = arrayUtils.map(Fiberlayer.layerInfos, function(info, index) {

if (info.defaultVisibility) {

visible.push(info.id);

}

return "<input type='checkbox' class='list_item'" + (info.defaultVisibility ? "checked=checked" : "") + "' id='" + info.id + "'' /><label for='" + info.id + "'>" + info.name + "</label>";

});

var ll = dom.byId("layer_list");

ll.innerHTML = items.join(' ');

Fiberlayer.setVisibleLayers(visible);

on(ll, "click", updateLayerVisibility);

}

function updateLayerVisibility() {

var inputs = query(".list_item");

var input;

visible = [];

arrayUtils.forEach(inputs, function(input) {

if (input.checked) {

visible.push(input.id);

}

});

//if there aren't any layers visible set the array to be -1

if (visible.length === 0) {

visible.push(-1);

}

Fiberlayer.setVisibleLayers(visible);

}
