Problem with read()

I have a little problem with the read() command

For testing, I made this:

print "1 = ?" --Answer is 1
input = read()
  if input == 1 then
	print "Yes"
  else
	print("No" .. input .. "isn't 1"
  end

If I then type in 1, it says "No 1 isn't 1"
I have no idea why.
Could somebody help me here?

read always returns a string. Either compare input to a string, like "1", or pass input through tonumber() first, ex, local input=tonumber(read())

oww… ok
Didn't know that's a string.
Thanks

Or just quote the 1:P

if input == "1" then

or

input = tonumber(read())

because "1" isn't 1, but tonumber("1") == 1
