How can I make my Health Game pass compatible with this Dev product script?

So I am wondering how I could make these two script compatible. Dev script that allows Developer Products give stats:

local MarketplaceService = game:GetService("MarketplaceService")
local AddHealthID = 22137556 --ENTER 
local AddSpeedID = 22137544  --PASS
local AddGearID = 22137570   --IDS
local AddGear2ID = 22137564   --IDS
local AddGear3ID = 22137575  --HERE
local AddGear4ID = 22137566   --IDS
local PurchaseHistory = game:GetService("DataStoreService"):GetDataStore("PurchaseHistory")
MarketplaceService.ProcessReceipt = function(receiptInfo) 
    local playerProductKey = receiptInfo.PlayerId .. ":" .. receiptInfo.PurchaseId
    if PurchaseHistory:GetAsync(playerProductKey) then
        return Enum.ProductPurchaseDecision.PurchaseGranted
    end
    for i, player in ipairs(game.Players:GetPlayers()) do
        if player.userId == receiptInfo.PlayerId then
            if receiptInfo.ProductId == AddHealthID then
				player.Character.Humanoid.MaxHealth = player.Character.Humanoid.MaxHealth + 50 --Adds 50 to their current health
				player.Character.Humanoid.Health = player.Character.Humanoid.MaxHealth
			end
			if receiptInfo.ProductId == AddSpeedID then
				player.Character.Humanoid.WalkSpeed = player.Character.Humanoid.WalkSpeed + 15 -- Adds 5 to their current Walkspeed
			end
			if receiptInfo.ProductId == AddGearID then
				game.ReplicatedStorage.GravityCoil:Clone().Parent = player.Backpack -- put the gear in ReplicatedStorage then put the name of the gear in the GEARNAMEHERE
				-- game.ReplicatedStorage.GEARNAMEHERE:Clone().Parent = player.StarterGear -- Add this back in if you want them to get this item till they leave the game, Like renting it
			end
			if receiptInfo.ProductId == AddGear2ID then
				game.ReplicatedStorage.LockonLauncher:Clone().Parent = player.Backpack -- put the gear in ReplicatedStorage then put the name of the gear in the GEARNAMEHERE
				-- game.ReplicatedStorage.GEARNAMEHERE:Clone().Parent = player.StarterGear -- Add this back in if you want them to get this item till they leave the game, Like renting it
			end
			if receiptInfo.ProductId == AddGear3ID then
				game.ReplicatedStorage.JetPack:Clone().Parent = player.Backpack -- put the gear in ReplicatedStorage then put the name of the gear in the GEARNAMEHERE
				-- game.ReplicatedStorage.GEARNAMEHERE:Clone().Parent = player.StarterGear -- Add this back in if you want them to get this item till they leave the game, Like renting it
			end
			if receiptInfo.ProductId == AddGear4ID then
				game.ReplicatedStorage.EpicLaser:Clone().Parent = player.Backpack -- put the gear in ReplicatedStorage then put the name of the gear in the GEARNAMEHERE
				-- game.ReplicatedStorage.GEARNAMEHERE:Clone().Parent = player.StarterGear -- Add this back in if you
			end
		end
	end
    PurchaseHistory:SetAsync(playerProductKey, true)	
    return Enum.ProductPurchaseDecision.PurchaseGranted	
end

My script that adds Health when you buy a Gamepass:

gps = game:GetService("GamePassService");

id = script:WaitForChild("GamePassID");
EH = script:WaitForChild("ExtraHealthAmount");


game.Workspace.ChildAdded:connect(function(char)
h=char:FindFirstChild("Humanoid")
if h~=nil then
plr=game.Players:FindFirstChild(char.Name)
if gps:PlayerHasPass(plr, id.Value) then
h.MaxHealth=EH.Value
h.Health=EH.Value
end
end
end)

When you use the Game pass it does give you +150 Health but when you try and buy +50 Health from the Dev Product it does not add anything since the Health Game pass sets the health. I need it to add the Health instead of setting it. Goulstem helped me do the same exact thing except with Speed not health and here is the script that he helped me on that works so I am figuring that the script for this on will be very similar:

local gps = game:GetService("GamePassService");
local id = script:WaitForChild("GamePassID");
local Speed = script:WaitForChild("WalkSpeedAmount");

game.Players.PlayerAdded:connect(function(Player)
    Player.CharacterAdded:connect(function(char) --CharacterAdded event
        char:WaitForChild("Humanoid") --Just to be safe(;
        if gps:PlayerHasPass(Player , id.Value) then
            local hum = Player.Character.Humanoid
            hum.WalkSpeed = hum.WalkSpeed + Speed.Value
        end
    end)
end)

If forgot to mention that the Health Game pass has a Value names GamePassID and ExtraHealthAmount. If you can help it would be really nice of you! Plus I want the person to have the extra health everytime the are respawned!THANKS!

By the way if you see this Goulstem sorry, I sent you a message on ROBLOX to further explain the situation and to say sorry:)

if u want them to stack (thats wat I think ur problem is) then don't do

Humanoid.Health = 150

do

Humanoid.Health = Humanoid.Health + 150

and then for the Dev Products as well

Humanoid.Health = Humanoid.Health + 50

EDIT: I see u also want it on Respawn

game.Players.PlayerAdded:connect(function(plr)
	plr.CharacterAdded:connect(function(char)
	--check if player has Pass
	--then insert the lines that I gave above (h.health = h.health + watever)
	end)
end)
