An add on comment. This problem does not exist in MS Publisher 2000.

Centering in 2002 is very difficult if possible at all. This is due to the
use of CSS 2 with absolute positioning. (see www.w3c.org) and in fact the
use of the center tag is deprecated.
Looking at your sites code I see you are using 2002 in it's original state
which is a big mistake. You need to load Service Packs 1 and 2 asap. See my
sites 2002 section for details.
Once you resave your pages in 2002 SP 2 you'll probably see some difference
in the output. As for code fragments, those are coded relative to where you
put the fragment box on the page. Draw the fragment in the center of the
page and you should get the output close to that. That said it's not quite
that simple it does depend on the code in the fragment and the code outside
the fragment.
Looking at your code I think you care using a center tag in the fragment, I
suggest removing that as all it does is center the search box inside the
table cell, it has no effect on the centering on the table or cells.

Thank you David. I have installed Service Pack 1 and ordered Service Pack 2
CD since it is 50 mb and will take too long to download on dial up. However
it is back ordered, so who knows how long I will have to wait. If anyone has
one I would be most appreciative to receive it.
