Getting the horizontal position of an object..?

I use...
document.all[img].offsetTop
...to get the verticalposition of an image.
Q: What do I use to get the horizontal position? I tried what I thought was the obvious:
document.all[img].offsetLeft
...but it didn't work. Hope you can help, thanks/Per

object.offsetLeft should work. But be careful, offsetTop and offsetLeft are relative position indicators. If your object is nested, the values are relative to the nesting object.

How does your object looks like?

(I suggest you to use document.getElementById(id) method instead of document.all)
