Help with KGC_RankConception script

[Keyren]

Hi!!I found this Japanese script, which lets you change the position of the character in battle(front, middle and back) is the option you choose in the database ]in the section class.The script works, but I do not know how to change the position in battle, as I understandwe need to create a skill and some attibuti in the System section of the database, but after many attempts did not succeed. Maybe a more experienced person can understand something =) thanks in advance^^
