Edit: problem solve  How to solve this problem, just add new function on luafile514\lua files\SkillInfoz\skillinfo_f.lub GetSkillScale = function(in_SKID, in_Level) local obj = SKILL_INFO_LIST[in_SKID] local x = 0 local y = 0 if nil ~= obj then obj = SKILL_INFO_LIST[in_SKID].SkillScale end if nil ~= obj then obj = SKILL_INFO_LIST[in_SKID].SkillScale[in_Level] end if nil ~= obj then x = SKILL_INFO_LIST[in_SKID].SkillScale[in_Level].x if nil == x then return 0, 0 else
