Macro to auto Update values in different sheets

Hi masters!!, It's Wednesday! !

I've searched the information, but cann't find how to auto update if I change a value in the cells.

For example:
If I have a value on Sheet 3 and modified it (Name), I need a function that find the old value that had originally and replace it on the sheet 2, is this possible?


attach the file for more explication..

Thanks a lot!
Best Regards!
