In dreamweaver I also added flash media buttons and they wont show either. Everything shows only when I am in dreamweaver and I save and hit the prieview in a browser button. Please help any suggestions. my website is http://www.stevonation.com. here is a copy and paste of the current html. oh yeah I am using the design part of dreamweaver not actually entering in my own html. thanks for the responses any help would be great.
