Flash files not seen by some

[SBO]

I have developed my website with FrontPage 2003 and have a few flash files. I'm finding out that most users are able to see the files, however there are a few that cannot. Is this possibly because I haven't specified the DOCTYPE metatag???
What should my DOCTYPE be with the above HTML1, 2, .. ??

Can anyone help??

Flash 7 hasn't reached optimum market penetration yet. Make sure youe publish your Flash in player 6.

Next check to see how Frontpage is embedding the SWF.
You should manually insert the proper HTML generated by Flash.

Unfortunatly Frontpage tends to assume everyone should use Internet Explorer. Mozilla browsers recognize Flash with a different code.

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"

//Internet Explorer reads SWF here
codebase="https://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="975" height="500" id="home" align="middle">
<param name="allowScriptAccess" value="sameDomain" />
<param name="movie" value="your.swf" />
<param name="quality" value="high" />
<param name="bgcolor" value="#ffffff" />

//Mozilla browsers need this code format
<embed src="your.swf" quality="high" bgcolor="#ffffff" width="975" height="500" name="home" align="middle" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
