This article will explain what the field picker (FP) is, as well as provide you with an idea of what it can be used for.
Now that you now how to build a questionnaire and how to get respondents to fill it out, you obviously are aiming for the largest response rate possible. Personalization is a great way to appeal to your respondents and make them more likely to fill out the entire survey.
This is where the field picker comes in. The field picker is an awesome tool that allows the user to personalize emails, questionnaires, text fields and even reports! The field picker creates a placeholder with which you can create a link to a defined value within your data file or questionnaire.
Think about a scheduled invitation by e-mail, automatically addressing each respondent by their first name, or letting them know what store they visited. Or maybe you want to personalize the questionnaire by reminding the respondent of a previous answer (s)he has provided earlier. And how about an interactive infographic that shows actual personalized results to different users.
In short, using field pickers is an awesome way to personalize and professionalize your research!
