Code Input Combo Tutorial

[EXO Muffin]

Hey, would anyone help me with this?
I have my Rage Combo set so that every time you attack, the rage goes up, when you defend it goes down, when you flee, it empties, and when it's full; it makes you input a 3-digit number.
If you put in 123, for example, it checks if you have,"Focus Scroll 1," if you do then; it does the Rage Combo, if you don't, then it says,"Unknown Rage Combo. Need Focus Scroll."
What I don't know is how to make him do the attack. I'm using the DBS, but have custom coding input for Hikinzoku's HP, and the Monster's HP.

I've already checked Gaming World and Charas-Forums tutorials, already.

Please help!
