CSS menu problem

I having a problem with my dropdown css menu. It's displaying as a list instead of the dropdown as I needed it to. I have gotten this to work perfectly locally but on the web it just displays as a list. Also my images will not show up at all on the webpage even though it appears that they are all pointing to the right place.

here is a link to view the page. www.keepsafecanada.com/keepsafe/keepsafe.html

View source to see the code in question.
Also here is a link to the completed version locally.
