Mugen assistance

its my edited version of sean, it still has some kinks, im trying to add a charge move but it never works, could someone help me out
here is what i have so far

;Power Charge
[Statedef 850]
type = S
physics = S
movetype= I
anim = 957
ctrl = 0
velset = 0,0

[State 0, ChangeState]
type = ChangeState
trigger1 = animtime = 0
value = 958
ctrl = 1

[Statedef 958]
type = S
physics = S
movetype= I
anim = 958
ctrl = 0
velset = 0,0

[State 0, Explod]
type = Explod
trigger1 = (time%50)
trigger1 = numexplod (956) = 0
anim = 956
ID = 956
pos = -10,0
postype = p1
bindtime = 10
removetime = 10
scale = 1,1
sprpriority = 6
ontop = 1
shadow = 0,0,0
ownpal = 1
removeongethit = 1


[State 0, PowerAdd]
type = PowerAdd
triggerall = time > 9
trigger1 = 1
value = 2 * ((time+12)/12)


[State 0, PlaySnd]
type = PlaySnd
trigger1 = time = 1
value = 100,48
channel = 10
volume = 255

[State 0, PlaySnd]
type = PlaySnd
trigger1 = time = 1
value = 100,49
channel = 9

[State 0, ChangeState]
type = ChangeState
trigger1 = (Command != "charge_z" || Command != "charge_c") || power >= 3000"
value = 959
persistent = 0

[Statedef 959]
type = S
physics = S
movetype= I
anim = 959
ctrl = 0
velset = 0,0

[State 0, StopSnd]
type = StopSnd
trigger1 = time = 1
channel = 10
persistent = 0

[State 0, StopSnd]
type = StopSnd
trigger1 = time = 1
channel = 9
persistent = 0

[State 0, ChangeState]
type = ChangeState
trigger1 = animtime = 0
value = 0
ctrl = 1

==============================================================================


;Power Charge
[State -1, Power Charge]
type = ChangeState
value = 957
triggerall = var(59) != 1
triggerall = power < 3000
triggerall = stateno != 950
triggerall = var(20) = 0
triggerall = var(46) = 1
triggerall = (command = "hold_z" && command = "hold_c")
trigger1 = !var(59)
trigger1 = statetype = S
trigger1 = ctrl || stateno = [100,101]

This is the error i keep getting

If not misspelling in CNS, check CMD
