The only thing that appears "odd" to me is that you have a
quote nested
inside the
list. I've seen problems with doing things like that. Same problem occurs when nesting things in any programming method.
The very simple text 'editor' in most forum software doesn't usually offer much help in that sort of thing. It's all up to the poster to match the tag pairs correctly.
I could do it for you but I learn better by doing rather than by reading/hearing, so I'll let you do it yourself.
Just remove the quote from
within the list. Probably best to put the quote at the beginning of the post.
I suspect you are using the formatting buttons
after you've written the basic post. The formatting is so simple I find it usually quicker to just type the tags in where i want them as I'm writing the post. That way I don't have to be so careful about where and what I select with the mouse/track pad.
