Second test - data calculated correctly, labels are good. I am now copying the part of the project to be tested, transferring it to another computer and saving it as backups. The third test (upcoming) will be a far wider test of the file capabilities.

Raw spreadsheet converts directly to PDF file poorly; I have a workaround - I think, and it will be needed.

Improvements needed - I need to define areas in the spreadsheet to be used solely for numerical data entry. I'm not sure whether this will have a negative effect on printed or PDF output; time will tell.

Unexpected benefit - with the improvements in the formulae in this file creation of the new pages is faster than ever, shortening the time necessary to complete the project.
