You can check the input once the user typed it.
Example :local input = nil local minLength = 2 local maxLength = 10 while (input == nil or #input < minLength or #input > maxLength) do input = read() end
I think it should work as you expect.

No that won't because then you would have to type a char and hit enter before you can go on and you have no way to do a backslash.
It is possible but not that easy.
local input = nil
local minLength = 2
local maxLength = 10
while (input == nil) do
write("Pass : ")
input = read()
if (#input < minLength or #input > maxLength) then
print("Enter between "..minLength.." and "..maxLength.." characters please.")
input = nil
end
end

EDIT:
you seem to be using recursion also .-.
please dont call functions within itself, that causes problems
use loops instead or else the program will stack overdflow after awhile
Lua uses tail calls; what this means is that, if you call a function right after the return statement, the stack level will be re-used.function asd() return asd() end
return new()

Oh yes! Thanks!You should edit this line :elseif button == 1 and x >= LXmin and x <= LXmax and y >= LYmin and y <= LYmax then
You actually don't check your pass and user variables. If you want to show an error message, you have to check them.
