[Script] POKEMON Shiny gold X Lugia

[maxiex9]

I got the the "Silver Wing" but the event isnt activating.
The script of the event starts right before you enter the room here

'---------------
#org 0x78BA20
checkflag 0x112D
if 0x1 call 0x878BA60
checkitem 0x172 0x1
compare LASTRESULT 0x1
if 0x1 call 0x878BA50
setflag 0x112C
end

'---------------
#org 0x78BA60
release
end

'---------------
#org 0x78BA50
clearflag 0x112C
release
end

But when I go in the room it shows nothing the lugia code is this

'---------------
#org 0x822C9C
lock
faceplayer
checksound
pause 0x14
sound 0x4B
setvar 0x8004 0x0

clearflag 0x807
fadescreen 0x1
hidesprite 0x1
fadescreen 0x0
setflag 0x112C
setflag 0x112D
release
end

I have made no edits to the code or anything. Im new to the scripting aspect and just confused why this event isnt activating.

The only thing I can think of is the item needs to be in HEX? But that doesnt make sense since the HO-OH event works fine. Thank You for your guys help
