No, it wasn't pasted as garbage. What I put in the message is precisely what, if typed into Mathematica, will work. Try evaluating it. To your other comment, for anybody who would like to author help files, I encourage you to check out AuthorTools (which comes with v5). It has some tools which are helpful in this process. Sure, even with AuthorTools, there are still some hurdles to overcome in the process, and we are looking into those, but I wanted to make sure to plug AuthorTools since the helpful functionality that is in there is slipping under a lot of people's radar, I suspect.
