Re: Code Constantly Breaking
I had the same problem with IFrames and you need a plug in. Then you also need to tweak the syntax a little -you can't just pop it in unaltered.
See
http://doc.tikiwiki.org/tiki-index.php?page=PluginIframe&structure=Documentation
for iframe plug in for 3.0 (it looks like the plug in may now come with a 3.0 tiki install).
For older versions you'll need to download a file and upload it to a directory in your Tiki install before the in-page Iframe syntax will work:
http://tikiwiki.svn.sourceforge.net/viewvc/tikiwiki/trunk/lib/wiki-plugins/wikiplugin_iframe.php.
This last links to a page that actually has the code so you'll need to copy it and paste it in a new doc to upload. See this thread for more info on installing it:

Try http://doc.tikiwiki.org/tiki-index.php?page=Wiki%20Plugins for many more plug ins.
