Does "GetFocusedTextBox()" only work on textboxes named "TextBox"?

Hello i am currently working on a game and i had ran into a problem. I am generating a couple TextBoxes on another script and i wanted to do so that when you press "Return" key on the keyboard it would get you to the next textbox. All of my text boxes are generated with the name of "TextBox" and a number which goes from 0 to 209. My problem is that i am getting an error on this line:

local TextBoxFocused = UserInputService:GetFocusedTextBox()

The error says the following: attempt to index local 'TextBoxFocused' (a nil value)

If i understand correctly, it says that TextBoxFocused is nil. I tried with a text box called "TextBox" and it worked just fine but a text box with the number at the end gives me the error. Any clues why?

Script:

wait(0.02)
for i,v in pairs(script.Parent:GetChildren()) do

if string.match(v.Name, "TextBox") then

print(v.Name)

v.Text = ""

v.ClearTextOnFocus = false

end

end











local UserInputService = game:GetService("UserInputService")





UserInputService.InputBegan:connect(function(input)

if UserInputService:GetFocusedTextBox() ~= nil then

game:GetService("UserInputService").InputBegan:connect(onKeyPress)

end

end)



function onKeyPress(inputObject, gameProcessedEvent)

if inputObject.KeyCode == Enum.KeyCode.Return then

local TextBoxFocused = UserInputService:GetFocusedTextBox()

local CharacterAfterO = string.find(TextBoxFocused.Name, "o")

print(string.sub(TextBoxFocused.Name, CharacterAfterO + 2))

print("HI")

end

end

Please Help, Thank you
