Roblox gamepass VIP door error - old gamepass code?

Hello! I'm fairly new to coding in roblox so forgive me if this is a simple fix but I've been trying to fix this for days with no luck. Whenever I try to use my VIP door it seems Roblox is trying to get an Id from the old marketplace (seperate from gamepass marketplace). I don't know where I went wrong with my code but I'll paste it below and hopefully find a fix for it. I'd just like to be able to use my VIP door with my current gamepass Id

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

ItemID = 4840168 -- The ID of the Gamepass/T-Shirt.
OpenTime = 1 -- The time the door is open for.
OpenTrans = 0.5 -- The transparency of the door when it is open.
CloseTrans = 5 -- The transparency of the door when it is closed.
BuyGUI = true -- Set to false to stop the BuyGUI appearing.
KillOnTouch = true -- Set to false to stop players being killed when they touch it.

    for i = 1,#Table do
