A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
You are quite welcome, glad I could help.
As for the old workbook, I wouldn't bother as long as you have what you need. Files can become corrupt (well, not corrupt in the traditional sense, but odd rules start to apply to older files that don't make sense or apply to new files), and you never know what is attached to a workbook that you can't see. The "copy all sheets into new workbook," trick is one I use from time to time just to deal with an excel file that is unusually large or slow compared to how it should be. I don't know exactly what is happening in that situation, I just know the fix ;)
If there was some formula that was broken by doing that trick or you lost some data then it might be worth going back, but...
