How do I sum a number to just one specific number of a table

[WilhelmVonLutzow (kross)]

Essentially what I have been trying to do is displaying 3 numbers in a table called Hector3 in a text box, and whenever you hold A, it adds +1 to the 2nd value.

I’m only going to post a small part of the code since the actual holding down button fully works.

Full Script

local UIS = game:GetService("UserInputService")
local Hector3 = {0, 0, 0} 

local TextBoxOne = script.Parent.X

TextBoxOne.Text = tostring(table.unpack(Hector3))
interval = 0.5

local KeyDown = false
local function onInputBegan(input, gameProcessed)
	if input.UserInputType == Enum.UserInputType.Keyboard then
		if input.KeyCode == Enum.KeyCode.A then
			KeyDown = true
			repeat wait()
				print("Holding down A")
				Hector3[2] = Hector3[2] +1
				TextBoxOne.Text = table.unpack(Hector3)
			until KeyDown == false
			end
		end
	end

local function onInputEnded(input, gameProcessed)
	if input.UserInputType == Enum.UserInputType.Keyboard then
		if input.KeyCode == Enum.KeyCode.A then
			KeyDown = false
		end
	end
end

UIS.InputBegan:Connect(onInputBegan)
UIS.InputEnded:Connect(onInputEnded)

For some reason, absolutely nothing happens and the text just. I have a feeling that the issue is somehwere in the repeat until loop somehwere, just can’t figure out how to fix.

Managed to solve it myself

Solved

local UIS = game:GetService("UserInputService")
local Hector3 = {0, 0, 0} 

local TextBoxOne = script.Parent.X

interval = 0.5

TextBoxOne.Text = table.concat(Hector3 , ", ")


local KeyDown = false
local function onInputBegan(input, gameProcessed)
	if input.UserInputType == Enum.UserInputType.Keyboard then
		if input.KeyCode == Enum.KeyCode.A then
			KeyDown = true
			repeat wait()
				print("Holding down A")
				Hector3[2] = Hector3[2] + 1
				TextBoxOne.Text = table.concat(Hector3 , ", ")
			until KeyDown == false
			end
		end
	end

local function onInputEnded(input, gameProcessed)
	if input.UserInputType == Enum.UserInputType.Keyboard then
		if input.KeyCode == Enum.KeyCode.A then
			KeyDown = false
		end
	end
end

UIS.InputBegan:Connect(onInputBegan)
UIS.InputEnded:Connect(onInputEnded)
