white box when embedding flash

[jak6868]

Hi all, I'm seeing a plain white box when I embed a flash game.
I scoured the forum, and I've done the following:

flash is enabled in CP (in both bbc code section and posts section)

I then tried to put the following in a post hoping of course to see a playable game:
[flash=200,200]<iframe src="http://www.miniclip.com/games/polar-jump/en/webgame.php" frameborder="0" style="border:none;" width="550" height="550" scrolling="no"></iframe>[flash]

Got a white box.

I then tried the miniclip game mod (http://custom.simplemachines.org/mods/index.php?mod=809) and the exact same thing happened. Got a white box.

So - why does that white box appear? What is wrong? Thanks!

UPDATE: Solved.  Rather than [flash] bbc codes, I needed  [html] codes, like this:
[html]<iframe src="http://www.miniclip.com/games/polar-jump/en/webgame.php" frameborder="0" style="border:none;" width="550" height="550" scrolling="no"></iframe>[/html]

As I understand it, only admin can put in the html tag?
As I further understand it, the 'iframe on post mod' (here: http://custom.simplemachines.org/mods/index.php?mod=941) allows users to insert iframes but is a bit of a security risk?

Yes, only admins are allowed to use the HTML tag by default. You can enable it for everyone in Admin > Posts and Topics > Bulletin Board Code but it's not recommended as it can pose security issues.

Yes, the same applies if you allow your users to use HTML. I suggest keeping this for administrators only.
