My b2evolution Version: 2.x

I am trying to add a menu item using Free HTML. It works on 2 skins but not on Tsokolate. The link is below the menu line.
See http://www.mang-goproject.nl/evoblog/index.php?blog=10.
Can anyone help a 72 year old blog newbie.
Brilliant piece of software by the way, and I have tried a few.

thanks
