var iBottom = document.getElementById(Pane11ID).style.bottom;

The line above doesn't work. I can set using style.bottom but not get. Is there a way to get the value of style.bottom or equivalent?

Many thanks

can you send Pane11ID s html ? maybe i can help you..

Pane11ID  is an object in my javscript method. Its justs just a string value of the panel's ID. I know this fine cos I used an alert to see its value.

thanks

I don't think "bottom" is a property of style. If you're trying to get the bottom border reference try the following:

style.borderBottom

basically, I need to find out the position of the bottom of a div relatives to the page. Is there no attribute that details this? If necessary I can use the top position and add the height of the div. Any idea how I can determine the exact position of the div on the page?

You can try to set the DIV tags POSITION style property to ABSOLUTE and set it's TOP property.
