Embedding Flash .swf in Dreamweaver

I’ve finished my flash website. I just imported the “.swf” file into a dreamweaver “.html” document. When in design mode, I can see my “.swf” file work properly. But when I open it in internet explorer the “.swf” file doesn’t show up–the page is blank. I validated the code and found the problem: <embed> tag not found in currently active versions. [xhtml 1.0 translational]

I don’t know what to do. Does someone have some experience with this?
