In principle, the title already says what error is about. When the textbox is empty it gives this error. What to do? I will be grateful. Here is the script where this error occurs:

local ConvertFrame = script.Parent:WaitForChild("ConvertFrame")
local TextBoxConvert = ConvertFrame:WaitForChild("TextBoxConvert")
local FinallyValue = ConvertFrame:WaitForChild("FinallyValue")
local ButtonConvert = ConvertFrame:WaitForChild("ConvertButton")

local player = game.Players.LocalPlayer

local TimeStats = player.TimeFolder:WaitForChild("TimeValue")

local TimeChange = game.ReplicatedStorage:WaitForChild("TimeValueChange2")

local Amountt = 1

TextBoxConvert.Focused:Connect(function()
	
	TextBoxConvert:GetPropertyChangedSignal("Text"):Connect(function()
			
		FinallyValue.Text = TextBoxConvert.Text:gsub("%D+", "") - tonumber(Amountt)
		
	end)
	
end)

ButtonConvert.MouseButton1Click:Connect(function()
	
	local text = TextBoxConvert.Text
		
	TimeChange:FireServer(text)
	
end)

Mind telling on what line it is happening?

#3 
FinallyValue.Text = TextBoxConvert.Text:gsub("%D+", "") - tonumber(Amountt)

I’d say wrapping this around in an if statement

TextBoxConvert.Focused:Connect(function()
    TextBoxConvert:GetPropertyChangedSignal("Text"):Connect(function()
        local cleanedText = TextBoxConvert.Text:gsub("%D+", "")
        if cleanedText == "" then
            FinallyValue.Text = "Default Value" -- Set a default value when the textbox is empty
        else
            FinallyValue.Text = tostring(tonumber(cleanedText) - Amountt)
        end
    end)
end)
