It seems that your swf is fine, but issue is with your html and/or embed code. Can you give a link or post your html code. For a hint do recheck the positioning and height of the embedded swf and its parent containers in the html code.
I believe that Satyajit has got it right. The problem has nothing to do with the swf. If you post a link to your page or send the files, someone could immediately figure out the problem. So be our guest...
Hi, thanks everyone, I've figured it out actually, I had to set the width and the height in my php file.
Sorry for not posting that I've solved it.
That's nice. Go on and mark your post as "answered".
