hey,you can start off by reading the error messages , I see a extra anchor tag in your code and Managing vm without under score.
I’m pretty confident you can complete rest after seeing what you have completed till now

I’m stuck on 10 , i can’t seem to see what i’m doing wrong

well youve now that at point 10 youre stuck
10. Additionally, the navbar should contain link (<a>) elements with the class of "nav-link". There should be one for every element with the class "main-section".
and theres a hint of your error:
There should be one .nav-link for every element with the class of "main-section", and every .nav-link should be within #navbar : expected 12 to equal 10
you might need to look at that.
