Why is the spreadsheet locked?
The spreadsheets contain many complex algorithms and some cells are locked (with a password) to prevent accidental modification to the formulas.
If you would like to unlock the spreadsheet and make your own custom modifications, please contact us and we can arrange this for you (advanced Excel users only).
Please note: while we do our best to integrate new feedback and feature requests, we are unable to provide support for any custom modifications outside of the scope of the logbook features. See also: Support Limitations
