Hello...I want to make sure you understand that you do not have to view the map within Excel. The intention behind AWhere (one of them, at least) is to allow you to load up your boundary map layer (your AOI map layer in this case, which it sounds like you have already been able to get into AWhere)...and once you have that AOI map layer loaded in AWhere, you can then use AWhere's Data Connection capability to dynamically link the map layer to your Excel spreadsheet. With that dynamic linkage established, you can then edit the display of the map layer (within AWhere's map window, that is) to represent the data values coming over from your spreadsheet via the linkage.
Further to that, each time you update or make edits to your Excel spreadsheet, you can simply do a 'Refresh' of the data connection in AWhere, and the map (again, in AWhere) will be automatically updated to reflect the updated data values in your Excel table.
Please refer to this forum post for more about the Data Connection capability in AWhere, it may answer your questions (http://forums.awhere.com/forums/thread/74.aspx )
If what I describe above is not what you need to do...if you absolutely need to have your map displayed within your Excel environment, please reply and someone will try to help, but I am not sure that that is directly possible with AWhere as it is, out-of-the-box.
