Thank you! You are right about drilling a hole in the bubble. It should be the union operator instead of 'and' . I actually managed to bypass the problem by using complement cell, but thanks for pointing out the root cause, I would try it next time.

Thank you, that must be the mislead of user's manual. It said I should seldom using complement operator. Not only the last cell, several of them have problem. The vised would report error in red lines even using union operator, the complement operator for cell combination is the only way to...

Solved now, closed thread.

Thank you for your help . I may try tomorrow if our site do not abandon url sharing . This is my first time try to build such complex model, so I also have no idea about the level of errors.
