You need to enter the 16 digit code that identifies the Cryptopia account you are sending to in the Data/Openfield.
The 16 digit code can be found on the Cryptopia website when you click "Deposit" and choose "Bismuth".
It brings up a form with these fields:
Message (required):
xxxxxxxxxxxxxxxx (your unique 16 digit code - enter this into Data/openfield)
