Product Landing Page - no form appearing

I’ve added this line:

<form id="form" action="/submit">
       <input name="email" type="email" id="email" placeholder="Enter your email address" required />
     </form>

Test results:

:x: 7. My landing page has a element with a corresponding id=“form”.’
#form is not defined : expected null to not equal null

:x: 8. Within the form, there is an field with id=“email” where I can enter an email address.
#email is not defined : expected null to not equal null

It’s absent from the preview, too.

This is the link to my pen.

it is not possible to help you if you don’t share your whole project, like the link to your pen

This is the link: Link

you have mismatched tags and some
angular parenthesis missing (not closed tags)
I suggest you use an html validator, like the one inside codepen. There is an arrow pointing downward near the html box, from which you can access a drop down
menù, and there choose “Analyze HTML”, and fix the errors
