LO 7.0.3.1 Base on Mac OS 11.1 (Big Sur, second update)
This input attempts to refine the first earlier submission. The screen shots below will, I hope, illustrate the dilemma.

Details with previous questions:
Base unusable owing to several different Libre Office Java-related error messages which occur when trying to enter data/edit Table.

Have not included error messages (have screen shots), as am hopeful that answers to the 2 questions will resolve problem. (Also, I’m unsure at the moment how to include screen shots.)

Hello,

The Java installed will not work. See:

Your New Database states 42 because when creating if there is another with the same name (look for them & possibly delete unwanted) it adds an incremented number. Give your databases a meaningful name.
