HELP WITH POWER UP TRANSFORMATIONS! [RMMV]

Hi, I'm very new to RPG Maker (as well as making games in general) and I really need some help.

I'm trying to get a skill using Yanfly's "Power Up Transformations" tip to target all allies. But no matter what I do, it always ends up just targeting the user. Is there a way to get the skill to target all allies?

I'm using a modified version of the skill shown in this video

This is the code I'm using myself

<Before Eval>
var Instinct = 13;
var INS2 = 14;
var INS3 = 15;
var INS4 = 16;
var INS5 = 17;
var INS6 = 18;
var INS7 = 19;
var INS8 = 20;
var INS9 = 21;
var IN10 = 22;
if (user.isStateAffected(Instinct)) {
user.addState(INS2);
} else if (user.isStateAffected(INS2)) {
user.addState(INS3);
} else if (user.isStateAffected(INS3)) {
user.addState(INS4);
} else if (user.isStateAffected(INS4)) {
user.addState(INS5);
} else if (user.isStateAffected(INS5)) {
user.addState(INS6);
} else if (user.isStateAffected(INS6)) {
user.addState(INS7);
} else if (user.isStateAffected(INS7)) {
user.addState(INS8);
} else if (user.isStateAffected(INS8)) {
user.addState(INS9);
} else if (user.isStateAffected(INS9)) {
user.addState(IN10);
} else {
user.addState(Instinct);
}
</Before Eval>

Any help would be greatly appreciated.

On another note, I have absolutely no knowledge of programming, art, sound, storytelling, animation, music, or any real idea on where to start if I want to make an RPG (or any type of game in general), so I'll most definitely have many more questions in the future. Can anyone recommend a good place to ask for help once those questions arrive?
