my code

local debounce = false
local player = game:GetService("Players").LocalPlayer



userInputService.InputBegan:Connect(function(input, gameProcessedEvent)
        if input.KeyCode == Enum.KeyCode.R then
            if tool.Parent == player.Character and script.Parent.AmmoValue.Value < 30 then
                reload_sound:Play()
                script.Parent.AmmoValue.Value = 30 -- what i want to change
            else
