If your layout won't work right, here's some troubleshooting tips:
1. Make sure you merged all overrides correctly (see
http://www.livejournal.com/tools/memories.bml?user=everything_lj&keyword=About:+Help+for+Beginners&filter=all).
2. Make sure your HTML/overrides are correct (see
FAQ #189).
3. Make sure you
defined a website in your user info, especially if you are making a sidebar layout.
Note that 95% of the time, one (or more) of these 3 things is the problem.
