and tried using code below didn't work. trigger function buy self.

window.onload = sliding; var tags = new array('tag1','tag2','tag3','tag4','tag5','tag6','tag7','tag8');// list of headings var pics = new array('popout1','popout2','popout3','popout4','popout5','popout6','popout7','popout8');// list of images slide out  function sliding() {     (var = 0; < tags.length; ++i) {         document.getelementbyid('tag1').onmouseover =  setslideout(tags[i],pics[i]);         document.getelementbyid('tag1').onmouseout=  setslidein(tags[i],pics[i]);     } }

here full code 

window.onload = sliding; var tags = new array('tag1','tag2','tag3','tag4','tag5','tag6','tag7','tag8');// list of headings var pics = new array('popout1','popout2','popout3','popout4','popout5','popout6','popout7','popout8');// list of images slide out  function sliding() {   /*for (var = 0; < tags.length; ++i) {        setslideout(tags[i],pics[i]);   }/*/     document.getelementbyid('tag1').onmouseover = slideout;      document.getelementbyid('tag1').onmouseout = slidein; }/* function setslideout(tagsid,picsid){     document.getelementbyid(tagsid).onmouseover = slideout(tagsid,picsid); }*/  function slideout(){     //alert('over '+ lid);     if(currpos('popout1') < 200){         document.getelementbyid('popout1').style.left = currpos('popout1') + 10 + "px";         var timer = settimeout(slideout,10)     }else{         cleartimeout(timer);     } } function slidein(){     //alert('over '+ lid);     if(currpos('popout1') > 0){         document.getelementbyid('popout1').style.left = currpos('popout1') - 20 + "px";         var timer2 = settimeout(slidein,10)     }else{         cleartimeout(timer2);     } } function currpos(element){     return document.getelementbyid(element).offsetleft;  }

here im trying to http://signsourceak.com/index2.html (first link in drop down works )

here's version of code modified use closures, trick:

window.onload = sliding; var tags = new array('tag1','tag2','tag3','tag4','tag5','tag6','tag7','tag8');// list of headings var pics = new array('popout1','popout2','popout3','popout4','popout5','popout6','popout7','popout8');// list of images slide out  function sliding() {     (var = 0; < tags.length; ++i) {         document.getelementbyid(tags[i]).onmouseover = (function(j){              return function(){                 setslideout(tags[j], pics[j]);             }                })(i);         document.getelementbyid(tags[i]).onmouseout = (function(j){              return function(){                 setslidein(tags[j], pics[j]);             }            })(i);     }

}
