Hi Michael


Thank you for your advice.


The suggestion to use "Name index unique" doesn't work because I want a rejection message that precedes when the save command is executed.


Actually, the idea to solve this problem is according to the idea of ​​you and Peter, which is to display a number of names that are almost the same.
It's just that I myself couldn't make the logic programming myself.


Do you have that logic programming?


thank you
