I'm watching the Video Action Guide on using the spreadsheet to create a site blueprint (http://demo.sitesell.com/tier/tier-d.html
). It has Tier 2 and Tier 3 in the spreadsheet, and a cool way to switch views between them, but no way to add and organize Tier 4's? I'm on a Mac so I'm new to XLS. Has anyone added a Tier 4 column that works as well as the rest of the spreadsheet seems to, and could explain how with Open Office?
