That is a private company site so I'm not suprise.
I've pasted the HTML code with my original post, hope that hleps.

Question, does it require specific reference to have selectedIndex work? Do I need to define it? I'm not familiar with the selectedIndex so please advice.

Also, I see there has method like IE.document.getElementByTagName("select")("dxr_report").value = "file2", but I still get the same error message. Do you have any suggestion?

Thanks a lot for your reply
