running into error with submitting forms

i get an error in my code after i submit the form in the /name route, and when i check my cookies in the chrome devtools it defines the name but name is undefined

here is all my code:

router.get('/name', (req, res)=>{
    res.render('name');
});

router.post('/age', (req, res)=>{
    const name = req.body.name;
    res.cookie('name', name);
    //i think there is something wrong below here
    if(name){
        res.render('age', {name});
    } else{
        res.redirect('/name');
    };
});

block content
    form(action='/ask/name', method='post')
        label(for='name') Name:
        input#name(type='text', name='name', placeholder='John Doe')
        button(type='sumbit') sumbit

block content
    h1 okay #{name}, what's your age?
    form(action='/ask/age', method='post')
        label(for='age')
        input#age(type='text' name='age', placeholder="15")
        button(type='sumbit') Submit

Hey jason limmm 👋

I didn't create an entire project to test these snippets you've provided of course, so maybe there is more that I'm not seeing, but from your post's question and the code I can see it appears...

  1. The /name route does not have a POST route to take in that submitted form.

  2. The /age route does not have a GET route to show the user that second form.

  3. The /age POST route is trying to access the name variable that would have been submitted on the first page's form.

I would either combine this into one form, if possible, or save the value of your name field behind the scenes in that file once you make your POST route for /name so that you can utilize it in the other route later.
