What am i doing wrong?

i am working on a random add skill system. hereis what i have
hero1
Events
Unit - A unit enters lvzone1 <gen>
Conditions
And - All (Conditions) are true
Conditions
((Triggering unit) is in hero1) Not equal to True
(Owner of (Triggering unit)) Equal to Player 1 (Red)
(Hero level of (Triggering unit)) Greater than or equal to 10
Actions
Game - Display to Player Group - Player 1 (Red) the text: This unit is now yo...
Unit Group - Pick every unit in hero1 and do (Unit - Remove (Picked unit) from the game)
Unit Group - Add (Triggering unit) to hero1
Set randomskill1 = (Random integer number between 1 and 2)
For each (Integer randomskill1) from 1 to 1, do (Game - Display to (All players) the text: yes)
For each (Integer randomskill1) from 2 to 2, do (Game - Display to (All players) the text: no)

the result i espect is that when a unit with lv 10 or higher who is not in unit group hero 1 enter the zone, it will add the unit to group 1 and remove the exisiting unit in group 1. This part works, but then the ranom system part doesnt. I expect it to randomly choose 1 of the 2 options, but instead it activates both of them. which display the test yes and no. I am all stuck after spending hours trying to fix it, plz help

Just replace this:

With this:

It should work fine, but please use the [trigger] tags next time.
