Collection accepted to mongo but webpage does not display db


I am just getting started with meteor and attempting the todos tutorial. I am able to add to the collection successfully. I am not able to get it to display on the webpage.
I have read the other responses on the forum and checked for syntax errors and haven’t found any. I have even copied and pasted the entire code from the tutorial without success. Has anyone else had this problem and if so how did you fix it? I appreciate your consideration in advance.

      used this for insertion  -- >  db.tasks.insert({ text: "Hello world!", createdAt: new Date() }); 

used this command to ensure that it was in the db. --> db.tasks.find();

inserted a sort into the js.

tasks: function () {
return Tasks.find({}, {sort: {createdAt: -1}});
