Could you provide a script that displays different messages on different days (but within the same region)? Specifically:
* When entering reg1 during the first week, display message mes1.
* When entering reg1 during the second week, display message mes2.
* When entering reg1 during the third week, display message mes3.
* When entering reg1 during the fourth week, display message mes4.
* And so on.
Thank you in advance!
