no sound on site here is url

I was asked to post my URL for my site.
http:/www.geocites.com/walash8330/index.html

this is a site i made up for my students to access. some pages have music like
the hosptial and homepage but the others like the course syllabus says the
plug in did not download successfully and it shows on my manager site that it
did.

i have been working with this problem for weeks. i was advised to post my url
that you brains can figure out the html............. oh dear god please help
