How do i do this?

i'm probably a moron for asking this, but BAM! i am anyway. so here goes.

in a map i'm currently working on, i want to make a trigger so that whenever a hero owned by any player levels up, and that hero's level is equal to 10, to replace that hero with a new one. I'm trying to use a player-owned unit event to do this, but i can't seem to select "All players" as the owner of the units i want this to happen to. It only gives me the choices of player 1, 2, etc. , neutral hostile, passive, and victim, or "Owner of unit". Is there some way to do this, or will i have to make a seperate trigger for each player?

just do 1 trigger but you have to put (number of players) events, 1 for each player

my creeping suspicion has been confirmed, and BAM! I am, indeed, a moron. thank you for your help. if you are ever trapped in a burning building and i happen to be in the area, i will do my darndest to endeavor to save you.

Ok...question number 2 of the veris-is-a-moron question marathon:

i made a paladin, and a debug trigger to set his level to 10 at the beginning of the map. my previous trigger replaces him with an archmage, using the same relative life and mana, then is supposed to change the archmage's level back to 1. i've tried last replaced unit, last created unit, set hero level, and set hero experience. it just seems to ignore the 2nd action. it replaces the paladin with the archmage, but the archmage stays at level 10, much to my dismay.

anyone, anyone?

nevermind, i just made a create unit action instead
