Oh my god what does this mean?

[Lilith]

I was trying to get myself to register in a thai forum but they have question you have to answer... จงแต่งประโยคนี้ใหม่แล้วเติมในช่องด้านล่างให้ถูกต้อ ง "มะ-รึก-คะ-ทา-ยะ-วัน"

Can you please tell me what that means and what should i answer?

Thanks in advance

It asks for you to redo the sentence but as far as I can tell there is no sentence to rearrange so you must have gotten only part of the question.

จงแต่งประโยคนี้ใหม่แล้วเติมในช่องด้านล่างให้ถูกต้อ ง "มะ-รึก-คะ-ทา-ยะ-วัน" means "Redo this sentence and fill in the blank below correctly. "มะ-รึก-คะ-ทา-ยะ-วัน" is the name of the forest where the Lord Buddha often preached, the correct spelling is มฤคทายวัน which is prononced "มะ-รึก-คะ-ทา-ยะ-วัน". Perhaps they ask you to spell มะ-รึก-คะ-ทา-ยะ-วัน correctly.
