Slider Disappears when adding second image

After I used code that I'd found earlier in the forums (to resize the slider), the slider looks fine with a single image. When I add a second slider image, the slider disappears altogether?

Here is all of the custom CSS I've added in the Theme Options > Styling Options > Custom CSS box (in case one of these modifications is causing the problem):


.menu_container {
position: fixed;
width: 100%;
z-index:999;
}
hgroup {
margin-top: 60px;
}
#menu .ddsmoothmenu {
margin-bottom: 0px;
}

.menu_container {
border-bottom: 3px solid #1FB5AE;
}

.feature_blog_content ul li .post_image .post_comment, .content-bar .post .post_image .post_comment {
display: none;
}

.feature_blog_content ul li .post_content p {
height: 200px;
overflow: hidden;
}

.flexslider .slides img {
height: 600px;
}

.header_container.not_home {
background: url(http://208.76.80.11/~michall/wp-content/uploads/2014/05/subpage_header1.jpg) center #303030;
min-height: 250px;
border-bottom: 1px solid #686869;
}

.flexslider .slides img {
height: 600px;
}

.logo {
margin-top: 40px;
display:none;
}

.header_container.home {
background: none;
}

 

Hello,

Could you please tell us exactly what do you want to change in this theme and also share us your website link.

 

I am trying to add images to the slider using the Theme Options > Slider interface.

When I include one image, it displays perfectly. When I add a second image, the slider disappears altogether (and the three boxes area moves to the top of the page, directly below the menu)...

I have since changed themes, though, so this is not a big deal (I found that the InkThemes Woodpecker theme has better features for what I'm trying to do - and I love the subpage design of Woodpecker for the site I'm developing!)... so this isn't a problem anymore.

Thanks!
