You need to enter a 6 digit code, numbers or letter or both, in the 6 larger clock like numbers on the left. They are all set to 0 by default. So first you type in there, then you enter captcha details and press enter. If your code is wrong, you will see WRONG! spelled out in the area where there used to be 000000 or your answer. If you put in incorrect captcha, it will show in small red text below it. Once you have entered incorrect captcha you cannot enter new answers in the main fields anymore. Make sure you enter captcha correctly, and you will be rewarded with a link thay says try again, just below the large answer area.
