Scripts

Please tell me what is wrong with the script. When you enter a specific region, it resets, and a message appears. After clicking the 'OK' button, a battle against the dwarves begins, 6 objects disappear from the map, 1 message appears, I am given 15 scouts, a dialog box appears, I click on one of the answers, and none of them work, and the quest also does not appear in the active quests. I am working with the message box function with multiple answers for the first time.

----Battle with the Dwarves (Starting Location)-----
