How would I make this text box only accept numbers as it's text?
It's suppose to make a test equal to nothing if a player inserts letters etc.
1 | while true do |
2 | if script.Parent.Text == 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9 or 0 or " " then |
3 | else |
4 | script.Parent.Text = " " |
5 | end |
6 | end |

or is not written like this, it may sound right, but its not how lua works, it's supposed to be if script.Parent.Text == 1 or script.Parent.Text == 2 or script.Parent.Text == 3.. etc, plus there is nothing after your then. mixgingengerina10 223 — 5y

Use tonumber if it returns nil then wipe the text else just return and instead of using a while loop use GetPropertyChangedSignal on the TextBox's Text Prestory 1395 — 5y

01 | local textbox = script.Parent |
02 | local function onFocusLost (enterpressed) |
03 | if enterpressed then -- checks if the user has entered a number |
04 | if textbox.Text == "1" or textbox.Text == "2" or textbox.Text == "3" or textbox.Text == "4" or textbox.Text == "5" or textbox.Text == "6" or textbox.Text == "7" or textbox.Text == "8" or textbox.Text == "9" then |
05 | print("Player entered a valid number") |
06 | else |
07 | print("Player did not enter a valid number") |
08 | end |
09 | end |
10 | end |
11 | textbox.FocusLost:Connect(onFocusLost) -- this event let's the function run when the client loses their focus of the TextBox. |
So, i made the numbers strings, because the text of a textbox is always a string.
and i added the FocusLost event so that it would only run when the client has entered text in the textbox.

So what you want to do is use tonumber on the text box's text if it does not return nil that means the text box contains numbers but if it does return nil that means the text box contains another character which is not a number.
Another thing to note instead of using a while loop is use :GetPropertyChangedSignal on the text box's text which would fire this function every time the text changes.
1 | function NumberValidation () |
2 | if tonumber(script.Parent.Text) ~= nil then |
3 | return |
4 | else script.Parent.Text = "" |
5 | end |
6 | end |
7 |
8 | script.Parent:GetPropertyChangedSignal("Text"):Connect(NumberValidation) |

I want each box to only contain one number, and it can't be 0. Knqe 23 — 5y
