Problem for lua experts.

[Coca Cola]

Well , i made a script that a item when equiped give x skill and when desequiped the skill gets out.
i made by condition and aid , but when 2 items are equiped just one give the attribute. so i realized that the error was in param_subid and i tried to fix but wasn't sucsseed .. sorry bad english.
Take a look :

local maxSKILLBonus, conditions = 1150, {}

local conditions = {}
for i = 1, maxSKILLBonus do
	conditions[i] = createConditionObject(CONDITION_ATTRIBUTES)
	setConditionParam(conditions[i], CONDITION_PARAM_TICKS, -1)
	setConditionParam(conditions[i], CONDITION_PARAM_SKILL_MELEE, i)
	setConditionParam(conditions[i], CONDITION_PARAM_BUFF, true)
	setConditionParam(conditions[i], CONDITION_PARAM_SUBID, 1)
end

local conditions2 = {}
for i = 2, maxSKILLBonus do
	conditions2[i] = createConditionObject(CONDITION_ATTRIBUTES)
	setConditionParam(conditions2[i], CONDITION_PARAM_TICKS, -1)
	setConditionParam(conditions2[i], CONDITION_PARAM_STAT_MAGICLEVEL, i)
	setConditionParam(conditions2[i], CONDITION_PARAM_BUFF, true)
	setConditionParam(conditions2[i], CONDITION_PARAM_SUBID, 2)
end

local conditions3 = {}
for i = 3, maxSKILLBonus do
	conditions3[i] = createConditionObject(CONDITION_ATTRIBUTES)
	setConditionParam(conditions3[i], CONDITION_PARAM_TICKS, -1)
	setConditionParam(conditions3[i], CONDITION_PARAM_SKILL_DISTANCE, i)
	setConditionParam(conditions3[i], CONDITION_PARAM_BUFF, true)
	setConditionParam(conditions3[i], CONDITION_PARAM_SUBID, 3)
end


function onEquip(cid, item, slot)
print(item.actionid)
type_ref = string.sub(item.actionid,0,1)
value_ref = string.sub(item.actionid,2)
value_ref = tonumber(value_ref)
if type_ref == "1" then
		doAddCondition(cid, conditions[value_ref])
return true
elseif type_ref == "2" then
		doAddCondition(cid, conditions2[value_ref])
return true
elseif type_ref == "3" then
		doAddCondition(cid, conditions3[value_ref])
return true
elseif type_ref == "4" then
print(x)
else
return true
end
end
function onDeEquip(cid, item, slot)
doRemoveCondition(cid, CONDITION_ATTRIBUTES, 1)
doRemoveCondition(cid, CONDITION_ATTRIBUTES, 2)
doRemoveCondition(cid, CONDITION_ATTRIBUTES, 3)
return true
end
