Write It! Lessons Changing わ to は。

After figuring out how to use my English keyboard for Japanese, I began to complete the "Write It!" section of Module 1.1.  When typing out the answer for konichi wa as こんにちわ the module answer was こんにちは.  Is this an error or does "wa" magically mean "ha" and I'm just supposed to figure that out (excuse the slight sarcasm).

Hi Kevin, 

Thank you for your feedback. I have checked this with our tutor and it seems everything is correct. The "wa" in "Konnichi wa" is the particle "wa", which despite it's pronunciation, is spelled with the character for "ha."

I hope this helps!
