Can you make me a script to pickup apples into a screen gui?

Hi, i would like a script for my game... I want to pickup apples and put them in an not existing backpack ( a screen gui that says for an expample: 1/20 ), i would like that number to change whenever i click on an apple (add 1). Is that possible? Thanks if you can :D (btw the apples are called click)

examples of updating text for inv

--[[
make a value in the player for apples (leaderstats also work if you have that, otherwise make a value)
local script inside the text label
]]

local player = game.Players.LocalPlayer
local value = player.amountofapples -- current amount of apples 
local value2 = player.maxapples -- max amount of apples


-- one way (updates when apples change)
value:GetPropertyChangedSignal'Value':Connect(function() -- runs when amount changes
	script.Parent.Text = tostring(value) .. '/' .. tostring(value2)
end)

-- different way (doesn't check when it changes, updates rly fast)
game:GetService'RunService'.RenderStepped:Connect(function() -- runs every second the player is in game
		script.Parent.Text = tostring(value) .. '/' .. tostring(value2)
end)

example of picking up the apple

--[[
this would be a server script inside of the apple
]]

function pickUp(player)
	if player.amountofapples and player.amountofapples < player.maxapples and player.maxapples <= player.amountofapples + 1 then -- checks to see if apples go over limit
		player.amountofapples += 1
	end
	script.Parent:Destroy() -- deletes apple so they cant get again
end

-- if using proximity prompt you could do something like this
script.Parent.ProximityPrompt.Triggered:Connect(function(player)
	pickUp(player)
end

For a simplified explanation, you would just use values, like shown:

-- Make sure you have a click detector inside of your apple and put a script inside of the apple

--Click detector script
local Debris = game:GetService("Debris")
local prompt = script.Parent
local apple = script.Parent.Parent
prompt.MouseClick:Connect(function(plr)
local remote = game:GetService("ReplicatedStorage").Remotes.Apple -- locate the remote event
remote:FireClient(plr)
Debris:AddItem(apple, 0.01)
end)
-- local script 
-- Put this is starterGui 

local maxStorage = 20 
local apple = 0 
local remoteEvent = game:GetService("ReplicatedStorage").Remotes.Apple -- again, locate the remote event you want to fire
remoteEvent.OnClientEvent:Connect(function()
apple += 1 
local gui = nil -- Locate the gui you want to show
while wait() do
gui.Text = apple.."/"..maxStorage
end
end)

Tell me if you get any errors
