Reply To: Use reservation form as info demand?

I changed the texts in the call of the form, but after sending I receive the message:
Availability
Demand successfully sent!
Please continue.
Price: 0,00 €
It is the last line that I would like to hide.
If I accept multiple demands, the result is the same: price column with 0,00 € .

After the sending the calendar and the form do not show up any more. How could I automatically show them again?
