Ccoa CBS 3.04 EX Error

[groudyogre]

Im using ccoa's 3.04 EX battle system, and obviously it comes with the mog layouts. I don't know why, but suddenly I'm getting this error but, only when i set the layout type switch to off:

The line and surruonding lines are:

actor = $game_party.actors
actor_x = i * 160 + 12
draw_lay(actor,actor_x - 5,110)
draw_face(actor,actor_x,100)
draw_name(actor, actor_x, 0)
draw_hp(actor, actor_x, 32, 120)
draw_sp(actor, actor_x, 64, 120)

Any help appreciated. Thanks.
