As long as there is a blank space in A2:E100, it must be complete or it cannot be saved

Like file forum 1, it can be saved. Like file forum 2, it can’t be saved jumped out of the screen and said that it must be filled in before it can be saved.

Each line must be filled in, and there is no blank in it.

Any help is greatly appreciated

Actually there is only FORUM 1 file, FORUM 2 is just a reference example.

@JINDON GURU When I typed B6 and I took the SAVE button, there was no response, as if I felt it could be archived. Actually, I couldn't archive it and jumped out screen, and the filling was incomplete.

Is this not working?

Oh, thank you very much ! It's okay, I want to add REP. to you, but I can't add the same person, add it another day
