Item Combo problem(costume stone)

[Item Combo problem(costume stone)]

I can't get sorcerer stone's option. Doesn't increase psychic wave damage.

Did i make wrong script? 

-----------------------------------------------------------------------------------------------------

item_combo_db.conf 

{
    Items: ["Proffesor_StoneUpper", "Sorcerer_StoneGarment"]
    Script: <" bonus2 bSkillAtk,SO_PSYCHIC_WAVE,15; ">
},

------------------------------------------------------------------------------------------------------

item_db.conf

{
    Id: 29432
    AegisName: "Proffesor_StoneUpper"
    Name: "Proffesor Stone(Upper)"
    Type: "IT_CARD"
    Loc: "EQP_COSTUME_HEAD_TOP"
    Script: <" bonus bAspdRate, (getskilllv("SA_ADVANCEDBOOK")); ">
},
{
    Id: 29435
    AegisName: "Sorcerer_StoneGarment"
    Name: "Sorcerer Stone(Garment)"
    Type: "IT_CARD"
    Loc: "EQP_COSTUME_GARMENT"
    Script: <" bonus2 bSkillAtk,SO_PSYCHIC_WAVE,10; ">
},

------------------------------------------------------------------------------------------------

item_db2.conf is same item_db.conf

{
    Id: 29432
    AegisName: "Proffesor_StoneUpper"
    Name: "Proffesor Stone(Upper)"
    Type: "IT_CARD"
    Loc: "EQP_COSTUME_HEAD_TOP"
    Script: <" bonus bAspdRate, (getskilllv("SA_ADVANCEDBOOK")); ">
},
{
    Id: 29435
    AegisName: "Sorcerer_StoneGarment"
    Name: "Sorcerer Stone(Garment)"
    Type: "IT_CARD"
    Loc: "EQP_COSTUME_GARMENT"
    Script: <" bonus2 bSkillAtk,SO_PSYCHIC_WAVE,10; ">
},

Professor Stone(Upper) and Sorcerer Stone(Garment) are no problem. These do work well. Sorcerer stone's third, forth option are not scripted yet.

Anyone help me plz~

ps: Sorry for my english.
