do something like

if script.parent.Text = "1", "2"

Unless you have higher numbers than 1-2-3-4-5-6-7-8-9-0 that may be something else tightanfall 110 — 5y

yeah, with infinite numbers, good idea -_- SuperBeeperman 30 — 5y

String="124124"
if tostring(tonumber(String)) == "" then 
    print'not Number' 
else
    print'Is number'
end

That is how to detect if it HAS numbers

EDIT:

That was a joke.

here is how to make the textbox only contain numbers

textBox.Changed:connect(function(p)
    if p=="text" then
        textBox.Text = tonumber(textBox.Text)
    end
end)
