How to reply a message

Hi Bobbi and Nikolaus

Thank you for advising me. I will try and se, if it helps.
I haven't been sure how to do it, and the more I have seen the more I have doubted.

I have just replied - nor written any subject for my message, - just used the one,coming up.

And of course you are right. It will always cost a sum.

Regards
Jonna
