Creating difficulty setting

Hey, so I'm trying to make a difficulty setting like what's seen here: https://forums.rpgmakerweb.com/inde...a-difficulty-settings-without-a-script.21851/
but the states I made aren't being applied. Here's the battle event I made: I'm not sure why it's not working.(also I know I set it to the max difficulty at the beginning, that one buffs enemies max hp, so it's the easiest to notice when it's active).

none of the conditions matches the value of the variable.
that's why none of the states is being applied.

Your last Conditional Branch has a problem. You check the wrong variable.

1) you set the variable to 4, overwriting whatever other method of selecting difficulty you have.
2) you check the variable only for 1 to 3, having selected the wrong variable for the check against 4
