Using Entity Attacked procedure "amount" dependency is freezing the game

I'm trying to use the amount dependency to make a specific weapon do triple damage to undead enemies. I can use the amount dependency just to get the damage values, but when I use it to deal triple the damage, it freezes my game.

these are 2 different ways I did it.

If I use the "Before Entity is Hurt" global trigger, it totally breaks the game.

any solution would be appreciated.
