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 are an Advanced-Excel user and would like to unlock the spreadsheet in order to make your own custom modifications, please contact us and we can arrange this for you.
Disclaimer: while we do our best to integrate new feedback and feature requests, we are unable to provide warranty or Support for any custom modifications outside of the scope of the logbook features. See also: Support Limitations
