I'd suggest looking "under the hood" in one of these topics.
Depending on how these styles were applied (as well as how they
might have been applied in a pre-HTML life, such as Word), you
might see that the TrueCode manifests any number of SPAN tags, each
overriding the next, and not nested properly.
Then you could conduct radical surgery; that is, strip
everything but the opening and closing P tags. Then, you could
begin afresh.
You should probably also check the styles by opening your CSS
style sheet, and checking the logic in there (by the way, any
styles in the CSS will be overriden by styles contained in the HEAD
section of the topic, both of which will be overriden by style info
at a specific element.
Got all that?
If any of this is unclear, you might want to
Attach Code the TrueCode from one LI element in a reply, in
effect letting us look over your shoulder.
Good luck,
