Could someone please help with the answer to this question? (it as asked when signing up on http://kasetporpeang.com/forums/index.php?action=register)

ธงชาติไทยมีกี่สี (ตอบเป็นตัวหนังสือ) - I translate this to: how many colours does the Thai flag have? (the answer is using letters)

I have tried สาม, 3, and even three. What am I doing wrong?

Try 'three'.oh I see that you have. Perhaps they want 'three colours' the most likely thing that I do wrong is get the verification letters wrong but they don't look too bad.

have you tried ๓ ?

Found in the Thai WiKi.
