your code:
<param name="movie" value="LXH2.swf" />
and:
<object type="application/x-shockwave-flash" data="LXH2.swf" width="550" height="305">
is a relative link to the swf file.
it is looking for the swf file at:
LXH2.swf
but it does not exist there.
you will need to edit the path to properly point to the swf file.
