Teach OR Revisions

	As add-ins are revised, dates and the purposes of the revisions are listed below. To check the version of the add-in that you are using, find the date of the add-in by choosing the About Add-in item on the submenu for the add-in. If you find that you are using an older add-in than is available at this site, download the add-in. Add-ins are stored in the zip format, so you will have to un-zip the file. Once unzipped, replace any old add-ins of the same name. Otherwise, Excel may use the old version rather than the new.
