I Need Help Getting Rid of a Border--SOLVED

[urtead]

My account type is paid; my browser is Firefox 2.0; the theme I am attempting to customize is expressive and is called "River at Night"; and my journal can be found at urtead.livejournal.com. My problem is that I cannot seem to get rid of the border that separates the alpha and beta columns. Any help would be appreciated. Here is the css for the customizations that I have done so far, though it has been mostly background changes:



#header-inner {
background-image: url(http://i279.photobucket.com/albums/kk143/urtead/sunclouds.jpg);
height: 300px;
}

#header, #header-content {background-image: none;}

.widget {border-bottom: none; }

#page-inner {background-color:#000000;}

#container {background-color:#000000;}

#container-inner, #header-inner {width: 1024px;}

#alpha {width: 834px;}

.layout-tw #alpha-inner {width: 794px;}

#alpha-inner, .asset-inner {border: none;}
