Validation errors in html site (Error) : I am in the last stages of development on my site. When I try to validate my page using w3cvalidator the following errors are displayed. However when I try to action the following below; closing the </nav tag this only creates more errors. 

Is there a quick fix for this? Ideally, I would like my page to validate 100%. 

W3c Validator Errors below.
