Retrieve Data with multiple choice lookup table

I have a register that actually register person A and person B into it

With the followup form, they both have to enter for exemple data A - 1 A- 2 A- 3 for A and B-1 B-2 B-3 for B, then i Try to retrieve the six values with a lookup table in anothor followup form, I only get the last two enters, A-3 and B-3.

How can I get all the value? and then choose between the six instead of the last two
