Horizontal menus not working with wp_nav_menu function

My horizontal menus work fine in static implementation but are not displaying as horizontal when using the wp nav menu array
<?php wp_nav_menu( array( ‘theme_location’ => ‘primary’)); ?>

see working usage: http://howlingwolfmedia.com/wp-content/themes/custom3/index_menuTest.html
now with wordpress tag inserted:
http://howlingwolfmedia.com/site3
the menu does not use the display:inline style

Not sure how to write the tag in my nav area:

<div id="navcontainer">
<div id="menusimple">
<ul>
<li>
		<a class="active" href="#">Navigation</a>
		<?php wp_nav_menu( array( 'theme_location' => 'primary',  'container' => 'navcontainer', 'container_class'=> 'menusimple' )); ?>
</li>
</ul>
</div> <!-- menus -->
</div><!-- navcontainer -->

most of the styling works except the inline display css. It’s just defaulting to vertical in the WP implementation.
styles use only 2 classes: 1 for container, other for ul li elements.
It works fine as static implementation:

menu style follows:

#navcontainer {
	position: relative;
	width: 100%;
	background-image: url(../img/navbar_yelloworange.gif);
	background-repeat: repeat-x;
	z-index: 200;
}

#navcontainer li {display: inline; } /* test for wp tags */
#menusimple li {display: inline; } /* test for wp tags */

#menusimple {
	width: 935px;
	height: 33px;
	position: relative;
	margin-left: auto;
	/* doesn't work  margin-right: auto; */
	}

#menusimple ul,
    #menusimple li,
    #menusimple span,
    #menusimple a {
		margin: 0;
		padding: 0;
		position: relative;
		z-index: 10;
    }
#menusimple:after,
#menusimple ul:after {
		content: '';
		display: block;
		clear: both;
    }
#menusimple a {
		color: #2c353e;
		display: inline-block;
		min-width: 2em;
		text-decoration: none;
		line-height: 1.8em;
		padding: .2em  1em  .1em  1em;
		margin: .2em  .0 .1em  0;
    }
#menusimple ul {
      list-style: none;
    }
#menusimple > ul > li {
		float: left;
		font-family: Verdana, Trebuchet, Sans-Serif;
		font-size: 1.2em;
		font-weight: bold;
		background-image: url(../img/navlink.gif);
		background-repeat:no-repeat;
    }
#menusimple > ul > li.active a {

    }
#menusimple > ul > li.active a:hover {
		background: #fff;
    }
#menusimple > ul > li a {
		background-image: none;

    }
#menusimple > ul > li a:hover {
		background: #fff;
    }
#menusimple > ul > li:first-child a {
    }
#menusimple > ul > li:last-child a {
		border-right: none;
    }
#menusimple li:hover ul {
		display: block !important;
    }
#menusimple li ul {
		display: none;
		position: absolute;
		text-align: center;
    }
#menusimple li ul li {
		display:block;
		width:200px;
		margin-top: -2px;
		padding-left: .2em;
		border-top: 0;
		border-left: 1px solid #000000;
		border-bottom:1px solid #000000;
		border-right: 1px solid #000000;
		background:#c6cad2;
		text-decoration: none;
		font-weight: normal;
		color: #000000;
		text-align: left;
    }
#menusimple li ul li a {
		display: block;
		font-size: .9em;
		border-right: none;
		border-bottom: 1px solid #ccc;
		/* border: 1px solid #f00;*/
		padding-left: -1px;
		margin-left: -1px;
    }

#menusimple li ul li:last-child a {
		border-bottom: none;
