BOG FP Reservation Question

[TexasLu]

When I entered the reservation number, I made a mistake and entered the reservation number for the second part of our stay (we are split AOA/POR). Now the only dates that will allow selections are for the days we are at POR. We were wanting to go on one the days that we are staying at AoA. I can't figure out how to change the reservation number. I tried logging out and then back it, but I never get the screen where you enter the number.

Does anyone know how I can correct my error?

Thanks,
Lu
