having some issues with a navigation menu. have 7 pages defined in WP and would like a nav button for each page, but am limited (somewhere in the code to only having 5 nav buttons. found the snippet below in the header.php file which i thought was the limiting culprit, but when i change the number=6 to 8 or 10, i still don't get any additional nav buttons. i searched though the .css files as well and did not see anything remotely related to nav, only formatting (colors/font/size) type of variables. am i looking in the right place? can you point me in the write direction?
<ul id="nav">
<li <?php if(is_home()) {?>class="current_page_item" <?php } ?>>/">Home
<?php wp_list_pages('depth=1&number=6&sort_column=menu_order&title_li=' ); ?>
