CSS navigation issues and image sound

CSS navigation issues and image sound

I'm currently working on a site which is very basic. and its has 2 issues.
I've uploaded my site. which is being edited until its fully working. The
intro page works fine which is the index. html page. Then second I click
on my sites menu bar for HOME it loads home. While on HOME I want to go to
INTRO. To see if the link works. instead loading intro page as it does
when I load site for first time. It loads the WEBHOST site page? Can
anyone pass on any clues as to why this happens.
Also my second question is when putting together my profiles page together
of the cast of the A-TEAM show. With images on left column underneath each
other running down page and text on right same way as pictures. I want
each image to be clicked on to play the sound. I don't want no in browser
players or anything else. just click image play sound. were do I put the
code and can how I make it work for the 5 images that need audio linked to
them?
