New menu on the Top

Hello,

I would like to know how can I make a new menu on the top.

I have done a standard-menu (mainmenu) with 4 items
and I try to do a second menu on the topside, but it doesnt show up.

You can see the pictures.

Maybe I have to change the Layout.css, but I dont understand very well all about css.

Can you help me

I thank you in advance

Edu
