still getting a 404 page

Setting up a parameter route in this tutorial, I'm still getting a 404 and I don't know why. I've followed Andrew's step-by-step in the video, but my eyes can't figure out what I'm doing wrong. Here's a screenshot. Any ideas? Thanks!

Yeah, after this video that is how the code sits. We setup a route for /cards/:id but that overwrote our original route for just /cards.

Since no match to /cards exists anymore, when you try and navigate there the server sends the 404 page.

It might make it easier if, instead of changing the existing route for cards/ in the video, we copied that into a second route above with cards/:id. That way when you are finished with this video you will get a correct route even without providing an ID in the URL.

Hmmm, so 'cards/1' and 'cards/2' and so on work fine, but '/cards' gets the 404, but maybe it's supposed to be that way and I just misunderstood Andrew. Thanks again for looking at it! :)

Your right Brian, I had an issue with this as well. Earlier in the video Andrew tries to load the /cards/1 url which brings up a 404 error, which we then resolve. I was under the impression also that we were loading the cards page not the individual questions. Which led me to your question - have a feeling were not the only ones :)

Have you restarted your server? What is the route you are typing in? Are you doing /5 where 5 would be the id?

Hi Alexander, I did restart the server, but when I pull up http://localhost:3000/cards like what Andrew does at the end of the video tutorial, I still get a 404 screen. Not sure why.

Hmm. Are you importing your route in the app.js? 

const cardsRoute = require('../cards.js'); //example route only as I don't know where yours is
app.use('/cards',cardsRoute);
