Here is the script code:
```
function mes1()
MessageBox("Maps/SingleMissions/nasledieshantir/mes1.txt");
Trigger(REGION_ENTER_AND_STOP_TRIGGER, "sar", nil)
end;
Trigger(REGION_ENTER_AND_STOP_TRIGGER, "sar", "mes1");
```
The console displays a message that the message is empty when entering the specified region. Another script, which should give the player a quest when entering the same region, works normally.
