How MashZone NextGen accesses spreadsheets determines whether the data from the spreadsheet is a simple snapshot or is dynamic.

If the spreadsheet is located on your computer or on a network drive, MashZone NextGen takes a snapshot of the data when you register the spreadsheet. Updates to your spreadsheet are not automatically visible in MashZone NextGen. You must re-register the spreadsheet to update the data in MashZone NextGen in this case.

If the spreadsheet is hosted in a content management system, such as SharePoint, or is simply accessible with a URL using HTTP, MashZone NextGen links to the spreadsheet rather than copying data. Each time users use the spreadsheet mashable in MashZone NextGen, MashZone NextGen retrieves the current data from the spreadsheet dynamically.
