values display in column

Question

Hi i have designed infopath form. There are two columns:

1. Column A (Drop-Down)

      Values: Others

                     1

                     2

                     3

                     4

                     5 

2. Column B (TextBox)- If Select "Others" from Column A then Column B will apprear and allow enter to value

 

when i submit form it display in SP list -Column A- Others

 

Trying to do whenever Column B appear after submit the value, that value also save in Column A.

 

It means Column A & Column B value would be save in Column A only and display in SP.

 

Thanks
