did you enter that exactly as above or did you leave out the [[[ ]]] brackets?

When you enter the text into the HTML tool of the SCC programs, it puts those brackets in for you, you don't need to put them in as it will then double them and not work correctly. This may not be the case but I thought I'd mention that just in case it was. I'm still trying to find my old notes on the centering, but it was a pretty simple centering code if I recall like:

<center>yourtexthere</center>

something really simple like that, but I don't have it installed at the moment since I took my shop down so I can't look at it right now. If I can't find the code or the reference here on the forums for it (which is where I found out how to do it too) I'll install it later and see if I can find the code in my old shop settups.
