[JASS] Alliance System

[jl_kosuke141]

So I downloaded this system made by MapperMalte which is Alliance System but when I placed it in my map and then compiled/saved it, this error appeared

Line 2116: Undeclared variable Allies

which is this one here

                                set Allies[i]=Allies[i] + 1

So I declared that variable by placing

local integer array Allies

which it worked but ingame I tried the "-ally 2" or "-ally 3" a text appeared saying that "Error - You can't ally everybody" even though I have no allies and there more than 2 players which is the condition that you can't ally when there are only 2 players.

Can anyone point out the problem here? And I'm not really good with Jass by the way. I've red the comments section of his map but no one else encountered this problem
