Hello,
I have a block with a surveypage that brances to several surveypages depending on how many radiobuttons are needed per page.
This is part of the data file where you can see that the value of the "radiobutton_1_1other" persists in the data unless it is changed.
The first time I have selected "Other" as an option and filled the textbox with the value "Other_2", while the second time I selected "book" but the "radiobutton_1_1other" has remained as "other_2" even though I didn't actually used the other textbox. How can I initialize the null value of the "radiobutton_1_1other" response, so when it is not used remains empty?
| BlockCode | TrialCode | Response |
| PK1_block | radiobutton_1_1 | Other |
| PK1_block | radiobutton_1_1other | other_2 |
| PK1_block | test_trials_part2_1_promptsoption1 | 1 |
| PK1_block | test_trials_part2_1_promptsoption2 | |

| PK1_block | test_trials_part2_1_promptsoption4 | |
| PK1_block | test_trials_part2_1_promptsoption5 | |
| PK1_block | radiobutton_1_1 | book |
| PK1_block | radiobutton_1_1other | other_2 |
| PK1_block | test_trials_part2_1_promptsoption1 | 1 |

Here is a sample of the code:

Your help is much appreciated.
Thank you in advance,
