Help! displaying games on a site

Arrrggghhh! I'm so frustrated. I am hoping 1 million great brains on chess.com can help out.

I am trying to turn annotated PGNs into "clickable" chess games to display on a Joomla web site. We started out using Chessflash (www.chessflash.com), which generates a block of code that you can drop into a web page. Looks good, works good....right until I go back into the joomla editor and make a change to the article and save it. Then the pgn data disappears and I'm left with a blank board. Duh!

Anyone have any experience with this or suggestions for good ways to display games on a Joomla site?

Thanks in advance!
