Thanks Peter! I got the website that you has introduced. But you didn't mind what I have asked. I seek help from the script that i had attached:

var ns4=document.layers
var ie4=document.all
var ns6=document.getElementById&&!document.all
function drag_drop(e)
{
if (ie4&&dragapproved)
{
crossobj.style.left=tempx+event.clientX-offsetx
crossobj.style.top=tempy+event.clientY-offsety
return false
}
else if (ns6&&dragapproved)
{
crossobj.style.left=tempx+e.clientX-offsetx+"px"
crossobj.style.top=tempy+e.clientY-offsety+"px"
return false
}
}
