Trying to enter our FF details at MMB, I get:

You have successfully entered the following Executive Club / Frequent Flyer numbers for booking XXXXXX
MR ROGER
Frequent Flyer Programme No details entered
Frequent Flyer Number No details entered
MRS ROGER
Frequent Flyer Programme No details entered
Frequent Flyer Number No details entered

Trying again, I get the same 'successful' message. Any idea how I can get them into the booking? Thanks. BTW, they are AA numbers.
