Why aren't any of collections being defined after publishing them?

I keep on getting these error messages in my browser console: 

Exception in template helper: ReferenceError: "CollectionNames" is not defined

The "CollectionNames" being all the collections I have in my app. I have researched but cant find a suitable solution.

My environment:
I am running meteor 1.2

The task.js file is where I define each collection. Below is the code in task.js

/myMeteorApp
--/imports/api/tasks.js 

import { Mongo } from "meteor/mongo";
import { Template } from 'meteor/templating';
import { ReactiveVar } from 'meteor/reactive-var';

Images = new FS.Collection("images", {
stores: [new FS.Store.FileSystem("images", {path: "~/uploads"})] });

buyList = new Mongo.Collection("BuyList");

WhoAreWe = new Mongo.Collection("whoDb");
merchantReviews = new Mongo.Collection("merchantReviews");

Messages = new Meteor.Collection("messages", {transform: function (doc) 
{ doc.buyListObj = buyList.find({sessionIDz: {$in: [doc.buyList]}});  return doc; }});

The server is where I publish the collections. Below is the code:
/myMeteorApp
--/server/main.js

import buyList from '../imports/api/tasks.js';
import Messages from '../imports/api/tasks.js';
import Images from '../imports/api/tasks.js';
import WhoAreWe from '../imports/api/tasks.js';
import merchantReviews from '../imports/api/tasks.js';

Meteor.startup(() => {
// code to run on server at startup

Meteor.publish('buyList', function(){
return buyList.find();
});


Meteor.publish('Messages', function(){
return Messages.find();
});

Meteor.publish('Images', function(){
return Messages.find();
});


Meteor.publish('WhoAreWe', function(){
return WhoAreWe.find();
});

Meteor.publish('merchantReviews', function(){
return merchantReviews.find();
});

});


And the client is where I subscribe for the collections. Find below the code:

/myMeteorApp
--/client/main.js

import { Template } from 'meteor/templating';
import { ReactiveVar } from 'meteor/reactive-var';
import './main.html';

Meteor.subscribe('Messages');
Meteor.subscribe('WhoAreWe');
Meteor.subscribe('Images');
Meteor.subscribe('buyList');

Where am I going wrong. I've been at this for many days now... Kindly help!

The collections must be defined on both the client and the server! Just import your collection names on the client side as well as the server:

import { buyList, Messages, Images, WhoAreWe, merchantReviews } from '../imports/api/tasks.js';

You still have to subscribe to the various publications of course.

It is a naming problem, when you publish the collection, you should refer to the collection name (messages), not the meteor variable (Messages)

Meteor.publish('messages', function(){...
