Help with my script and the new gamepass system. Can someone please help me?

I've tried fixing the script, but it just doesn't work for me. Can someone please help me with the script. Here's the script:

local Gamepasses = {
	
	
	[732884508] = { 
		1000000
	},
	
	
	[732884250] = { 
		"H:30",	
		"W:10", 
	},
	
	
}

local Items = { 
	[54529181] = {
		1000
	},
	
	
	[54529200] = {
		game.ServerStorage.Minigun
	},
	
	
	[54529215] = {
		"W:25"
	},

	[54529220] = {
		"H:25"
	}
}




local MarketplaceService = game:GetService("MarketplaceService")

function GetName(ID)
	if type(ID) ~= "number" then
		return
	end
	local sets = game:service("InsertService"):GetUserSets(ID)
	for k, v in next, sets do
		if v.Name == "My Models" then
			return v.CreatorName
		end
	end
end

local function Sep(table,plr)
	for i,v in pairs(table) do
		if type(v)=="userdata" then
			v:Clone().Parent = plr.Backpack
		elseif type(v)=="number" then
			game.ServerStorage.PlayerMoney:FindFirstChild(plr.Name).Value = game.ServerStorage.PlayerMoney:FindFirstChild(plr.Name).Value + tonumber(v)
		else
			if v:sub(0,2) == "W:" then
				plr.Character.Humanoid.WalkSpeed = plr.Character.Humanoid.WalkSpeed + tonumber(v:sub(3))
			else
				plr.Character.Humanoid.MaxHealth = plr.Character.Humanoid.MaxHealth + tonumber(v:sub(3))
				plr.Character.Humanoid.Health = plr.Character.Humanoid.Health
			end
		end
	end
end

local function SepQ(table,plr)
	for i,v in pairs(table) do
		if type(v)=="userdata" then
			v:Clone().Parent = plr.Backpack
		elseif type(v)=="number" then
			return
		else
			if v:sub(0,2) == "W:" then
				plr.Character.Humanoid.WalkSpeed = plr.Character.Humanoid.WalkSpeed + tonumber(v:sub(3))
			else
				plr.Character.Humanoid.MaxHealth = plr.Character.Humanoid.MaxHealth + tonumber(v:sub(3))
				plr.Character.Humanoid.Health = plr.Character.Humanoid.Health
			end
		end
	end
end

MarketplaceService.ProcessReceipt = function(receiptInfo)
	print(receiptInfo.ProductId)
	if Items[receiptInfo.ProductId] then
		if type(GetName(receiptInfo.PlayerId)) == "string" then
			wait()
			local p5 = game.Players:FindFirstChild(GetName(receiptInfo.PlayerId))
			wait()
			Sep(Items[receiptInfo.ProductId],p5)
		end
	end
	return Enum.ProductPurchaseDecision.PurchaseGranted		
end

game.Players.PlayerAdded:connect(function(p)
	if p~=nil then
		for i,v in pairs(Gamepasses) do
			if MarketplaceService:PlayerOwnsAsset(p,i) then
				Sep(v,p)
			end
		end
		wait(0.5)
		p.CharacterAdded:connect(function(c)
			for i,v in pairs(Gamepasses) do
				if MarketplaceService:PlayerOwnsAsset(p,i) then
					SepQ(v,p)
				end
			end
		end)
	end
end)

Note: W is walkspeed and H is health.
