| **Note:** Only the answer code is saved in the data record -- not the item text displayed (e.g. the selection option shown). If you want to change a selection option's text, you cannot directly differentiate afterwards in the data record up to what data record a participant selected the old option and from when the new one was selected. It always looks as if all participants have seen the last version of the questionnaire in the data record. Of course, you can indirectly track the time of the interview: in order to do so, you have to note the time the change was made manually. | **Note:** Only the answer code is saved in the data record -- not the item text displayed (e.g. the selection option shown).
