[Mediawiki-l] CSS troubles

[Dr. Nancy Dailey]

Hello to all. I am launching an educational wiki for women about personal finance (http://womensmoney.dbcity.com). I have created a custom skin and all was going well until now... 

In Firefox, the custom skin is showing correctly but all links are disabled in the content column. I cannot logon using Firefox.
In IE7.0 (still needs some layout fixes), all the links work but when I logon, the skin reverts to the Standard skin. 

I've scoured the main.css file to try to find my errors but my skill level with CSS and WikiMedia has failed me. Any help would be greatly appreciated.Thank you.
