/**** 퀵메뉴 ****/

#quick {position:fixed;top:140px;left:50%;margin-left:550px; width:120px; background:url

(../images/new/quicktop.png) top left no-repeat;}

.quick_levels{position:relative; height:215px; background:URL(../images/new/quicktop.png) top left no-

repeat;}/*background:#ffdf59;*/

/**** 퀵메뉴 ****/

#quicka {position:fixed;top:140px;left:50%;margin-left:550px; width:120px; background:url

(../images/new/quicktop.png) top left no-repeat;}

.quicka_levels{position:relative; height:215px; background:URL(../images/new/quicktop.png) top left no-

repeat;}/*background:#ffdf59;*/

.quicka_levels ul{}

.quicka_levels ul li{margin-left:65px; color:#fff; font-size:12px; font-weight:700;}

.quicka_levels .lev_bg{background:URL(../images/levels_bg.png) top center no-repeat; height:25px; 

color:#000; font-size:14px; font-weight:700;}

.quicka_margin {margin-bottom: 10px;}

이렇게 quick 는 기존 쓰는거고 quicka 로 다시 만들어서 

<div id="quicka">

<div> 

이렇게 하면 안되거든요..

<div id="quick">

<div> 

이건 되는데... 뭐가 문제일까요 ㅠㅠ
