Javascripts not initiating correctly

Thank you, I didn’t know about the script debug. Unfortunately, that didn’t help, and I know there aren’t any errors in the script already. The scripts themselves work, they just aren’t initiating correctly. Any other suggestions?

Hey guys, seriously thanks for trying to help, but does anyone have maybe a particular possible solution to my problem? I’m not trying to be sarcastic, but I have tried some of these things and I am aware that the codex exists. I’ve done a lot of searching.

Sorry, I should have included the code. Silly me. I can do a Fiddle, but since it won’t really work very well due to the animation. What is supposed to happen is a secondary header is supposed to pop down when the scroll hits > 542. That IS happening. Exactly how I want it to. The problem is on the window load, the bar itself is showing up until the user scrolls, then it disappears, and works correctly. If you scroll back up, it works well, still. Only on the initial load is the drop-down bar appearing incorrectly (it shouldn’t appear at all.

Here is the code:

<div id="follownav">
	<div class="follownavwrap">
		<nav>
			<div id="nav-logo-2"><a href="<?php bloginfo('url'); ?>"><img src="<?php bloginfo( 'stylesheet_directory' ); ?>/images/footer_logo.png" width="225" id="navv-logo"></a></div>
			<ul class="jsnav">
    			<li><a href="/companies">Companies</a></li>
    			<li><a href="/team">Team</a></li>
			    <li><a href="/global">Global</a></li>
			    <li><a href="/about">About</a></li>
			    <li><a href="/contact">Contact</a></li>
			</ul>
		</nav>
	</div>
</div>

#follownav {
	height: 70px;
	width: 100%;
	background: #000;
	position: fixed;
	top:0;
	z-index: 9999999;
	padding: 0;
	margin: 0;
}

.hide {
	display: none;
}

.show {
	display: block;
}

#follownav ul {
	list-style: none;
}

#follownav ul li {
	display: inline-block;
}

#follownav ul li a {
	display: inline-block;
	text-decoration: none;
	color: #fff;
	font-family: 'proxima-nova', sans-serif;
	text-transform: uppercase;
}

#nav-logo-2 {
	width: 200px;
	margin: 0;
	padding: 0;
	float: left;

}

.jsnav {
	width: 600px;
	margin: 0;
	padding: 0;
}

$(window).scroll(function(){
      if($(window).scrollTop() > 542){
          $("#follownav").slideDown("fast");
          $('#follownav').removeClass('hide').addClass('show');

      }
    });
    $(window).scroll(function(){
      if($(window).scrollTop() < 542){
          $("#follownav").slideUp("fast");
      }
    });

I should mention this is a custom theme, so I can’t switch themes.

@t-p, I built the theme myself..
