Table only shows in Firefox, can't get it to work

[srussian]

I've looked at the source code of http://www.clubguide.fi/coppermine/index.php dozens of times, then the theme.php, then the template.html. I cannot figure our why the top table is visible in Firefox but dissapears in other browsers.

If you check the website with Firefox and then another browser, you'll see what I'm saying. To make matters a bit more simple, I've attached the CLUBGUIDE theme to this post, please help me find a solution that's probably ridiculously simple.

Thank you in advance.

I'd start by using the WWW validator and correcting those errors.

Also use the WWW CSS validator and correct those errors.

You have tags that are improperly nested (open a <p> inside of a table, but closing it after the table closes; <b> with no </b>, etc).  You need to review your template.html and theme.php files and properly nest all of your html.  If you don't know much HTML, there are a lot of resources available on the web to assist you in learning HTML.

This isn't a really hard task, just a time intensive task.
