Setting of Random Enemy Steps in RPG Maker XP

First, find the lower left corner (that is, the list of maps), then click the map where you want to set monsters, and then press "Spacebar" or right click "Map Settings", a box will pop up with "Enemy Encounter Rate" on the right, double-click the blank place under "Team" (note that it should be set from the top layer to the bottom), and then select monsters and enemy encounter steps. Thank you~
