The problem is obviously related to the fact that the highlighted stuff is enclosed in {brackets} reserved for the smarty tags.
So here comes the question: Can someone help me solve this?

My real problem is, that the name of the video file to be played by this flash video player is included in the disappearing code... There is a possibility to get those config values from an external config.js, but the path of this is also enclosed by the same {brackets} (uh)
thanks in advance
