Hmm. . .
The html was off, so I switched it on, but it still doesn't work.
Im not too sure if shockwave will work on the forum.

hmm if you post it and then preview it before submitting, it shows the widget..but after, it goes back to the html, i guess flash doesn't work on here...i wouldn't see why it wouldn't though.

This totally sure the code is only you copy and paste in html editor and ready!
