Browser Works with Flash test movie btns but not in Dreamweaver

What changes need to be made?

The Broswer brings up this SE when testing flash btns in DW?

SecurityError: Error #2028: Local-with-filesystem SWF file file:///C:/inetpub/wwwroot/Pizzapal.co.uk/topFramebtns1.swf cannot access Internet URL http://mark-pc/Pizzapal.co.uk/index.html.

Thank you for reading
