Shror,
You don't need to know how to write a robot - the key here is SOMEONE
ELSE does. And it can be done very quickly, as Toby pointed out.
Did you try my suggestion of echoing both values to the screen instead
of doing a compare? See what they say?
Also - do you have all errors enabled?
Did you follow Toby's suggestion to search on CAPTCHA? There are a lot
of ready-made packages out there.
Instead of arguing with everyone, why not try some of the suggestions?
