Problem with validation

Hi,

We are trying to get the 'perfect' website up and running and someone
suggested that we first made sute that we got W3C compliant. Now we are
checking the scan tool :
http://lists.w3.org/Archives/Public/www-validator/2014Jun/0005.html. Now we
are getting some errors and some of them warnings. Maybe I am overlooking
something but how do we see the differrents between the types in the
overview? Thanks voor any reply!
