Problem reading variables in HTML. Help!

programming flash
1

The codes below works well in HTML, by passing user as Alvin.
No problem at all.

<param name=“movie” value=“myhobby.swf?user=Alvin”>
<embed src=“hobby.swf?user=Alvin”>

but when I want to put on the web it got problem loading/finding/using the variables… (I dont know the problem)

Is there any other way to pass in variables? Not using text file,
but passing in through HTML?

Example(I dont think this work but is there something like that?)

<param name=“user” value=“alvin”>
<embed src=“myHobby.swf”>

Thanks
