Trying to get maincenter centered. And mainleft and mainright to use the rest of the space that maincenter doesn't use.
And then how would I get a flash movie Inside of maincenter?
Thanks in advance.
Here is the code I am working with.

Code:
<html>
<head>
<title>Mike Owns?</title>

<style type="text/css">
	
	body {
		margin:0px 0px 0px 0px;
		padding:0px;
		}
	
	#mainleft {
		width:5%;
		height:100%;
		float:left;
		background:#fff;
		padding-bottom:10px;
		}

	#maincenter {
		width:800;
		height:100%;
		float:left;
		background: url(bg.jpg) repeat right; 
		padding-bottom:10px;
		}
	
	#mainright {
		width:5%;
		height:100%;
		float:right;
		background:#fff;
		padding-bottom:10px;
		}
	
</style>
</head>

<body>
<div id="mainleft">
</div>
<div id="maincenter">
</div>
<div id="mainright">
</div>
</body>
