请教！为何我的图片轮播代码在图片下方显示不了文字？
<SCRIPT   language= "javascript "   type=text/javascript>
var   imgWidth=365;                             //图片宽
var   imgHeight=120;                           //图片高
var   textFromHeight=0;                   //焦点字框高度   (单位为px)
var   textStyle= "f12 ";                       //焦点字class   style   (不是连接class)
var   textLinkStyle= "p1 ";   //焦点字连接class   style
var   buttonLineOn= "#f60 ";                       //button下划线on的颜色
var   buttonLineOff= "#000 ";                     //button下划线off的颜色
var   TimeOut=5000;                             //每张图切换时间   (单位毫秒);
var   imgUrl=new   Array();  
var   imgLink=new   Array();
var   imgtext=new   Array();
var   imgAlt=new   Array();
var   adNum=0;

//焦点字框高度样式表   开始
document.write( ' <style   type= "text/css "> ');
document.write( '#focuseFrom{width: '+(imgWidth+2)+ ';margin:   0px;   padding:0px;height: '+(imgHeight+textFromHeight)+ 'px;   overflow:hidden;} ');
document.write( '#txtFrom{height: '+textFromHeight+ 'px;line-height: '+textFromHeight+ 'px;width: '+imgWidth+ 'px;overflow:hidden;} ');
