How can i make jump counter to leaderboards in my game?

Here is the code:

game.Players.PlayerAdded:Connect(function(player)
    local leaderstats = Instance.new("Folder", player)
    leaderstats.Name = "leaderstats"

    local jumps = Instance.new("IntValue", leaderstats)
    jumps.Name = "Jumps"
    jumps.Value = 0

    player.CharacterAdded:Connect(function(character)
        local humanoid = character:WaitForChild("Humanoid")
        humanoid.StateChanged:Connect(function(_, newState)
            if newState.Name == "Freefall" then
                jumps.Value += 1
            end
        end)
    end)
end)

Create a value inside starterpack and just create a script that detects when the player jumps and adds 1 to the value remember to post question for help this is to help with errors not entire systems
