How do I make a script that counts the amount of digits in a value?

I want to make a keypad code, so how do I reset the code it the amount of digits in the value is > than 3?

How many digits?

Well, you need to use string.len

If the value is only digits, then you can get the length of the value, which will tell you how many digits there are.

Here's an example:

local Number = 73948329

local Digits = string.len(tostring(Number))

print(Digits)

I'm not a 100% sure on if this works, but try this:

local value = script.Parent.Digits.Value
if #value > 3 then
	print("Your code here")
end
