Still am getting murdered here

Yesterday I put up a post whereby I tried to show that nothing I have done seems to work and I mean nothing. I simply want a drop down nav menu to appear and nothing else.

I have 9 navigation buttons on my site. Of those 9 buttons, 4 of them currently have dropdown menus, the other 5 do not.

The nav button in question is #6 for Photo Gallery and the page is for The Virtual Tourist (a child page of Photo Gallery)

Photo Gallery is page 8.

So here is my code. Can anyone see what in the world is wrong and why this refuses to work?

First the stylesheet

#nav-04 ul {
	float: left;
	display: block;
	background-color:#ddd5c2;
	-moz-border-radius-bottomleft: 5px;
	-webkit-border-bottom-left-radius: 5px;
	-moz-border-radius-bottomright: 5px;
	-webkit-border-bottom-right-radius: 5px;
}

#nav-06 ul {
	float: left;
	display: block;
	background-color:#ddd5c2;
	-moz-border-radius-bottomleft: 5px;
	-webkit-border-bottom-left-radius: 5px;
	-moz-border-radius-bottomright: 5px;
	-webkit-border-bottom-right-radius: 5px;
}

As you can see it is identical to #4 which works perfectly

Next is the header.php The first is for nav 04 which works perfectly

<li id="nav-04"><a href="<?bloginfo('url')?>/events-and-attractions">Events & Attractions</a>
                        <ul>
							<? wp_list_pages('title_li=&child_of=28&depth=-1')?>
                        </ul>
                    </li>

Now for nav 06 which never works

<li id="nav-06"><a href="<?bloginfo('url')?>/photo-gallery">Photo Gallery</a>
					<ul>
							<? wp_list_pages('title_li=&child_of=8&depth=-1')?>
                        </ul>
                    </li>

I could REALLY use some help here as I have spent days upon days chasing this around.

Thanks, Mike
