Hi and please help!

I've got a procedure that opens an IE browser window to a specific web page
based on data from a cell and using

Set ie = CreateObject("InternetExplorer.Application")

but then I want to reuse the same IE browser window to repeat the procedure
using data from a different cell. I've tried using

Set ie = GetObject (, "InternetExplorer.Application")

but keep getting Error 429. Ideally I'd like to recognize the active IE
browser window by its Caption/Name because it remains the same for all data
used.

In other words, how do I tell Excel to look for a specific active IE browser
window before opening a new one, and while I have more than one IE browser
window open?

Thanks in advance for any help,

Brian
