Include, exclude and mimbo theme

Hello people

I have been trying to figure out the problem for two days now. I am using the theme called Mimbo / DEMO.

In the top is the menu, which is the pages being listed. I don’t want all of my pages to show up in the menu. I have tried <?php wp_list_pages(‘exclude=17,38’ ); ?> and <?php wp_list_pages(‘include=7,13,26,35&title_li=<h2>’ . __(‘Pages’) . ‘</h2>’ ); ?>, but none of them seems to work.

Can anyone please help me???
Thanks!!

Simon
