Use Trigger tags, it makes seeing what you have much easier!
I believe your problem is that you seem to have a variable named "PlayerLoopIntA" that's not what Xonok meant.
What they want is for you to go to the action called
-
-
For each (Integer BLANK) from 1 to 12, do (Actions)
-
Loop - Actions
BLANK should be a variable named LoopIntA of type Integer
-Next
Xonok is saying use an ITE statement to do a Race comparison
-Click on the blue "Race of Player 1 (Red)"
-Click on the blue "Player 1 (Red)"
-Click Function, scroll and find "Conversion - Convert Player Index To Player"
-Click on the blue "1"
-Select the LoopIntA variable you made prior
And now everything should be the same as Xonok had it!
(Be sure to change the create unit with the proper Player(LoopIntA))
