Instructions for using these programs are available on the first sheet of each file.

Please note that these spreadsheets are deliberately NOT locked down, so that users may adapt them should they feel the need. However, because of internal formulas, links and hyperlinks, changes to the spreadsheet can result in errors. Any changes should only be performed be experienced Excel users.

PLEASE SAVE A SEPARATE MASTER OF EACH FILE TO A SEPARATE STORAGE FOLDER IN CASE THE WORKING VERSION BECOMES CORRUPTED OR HAS DEVELOPED CRITICAL IRREVERSIBLE DELETION.
