How should the record value for the field e_first_name be formatted in a survey?

The correct formatting for the record value of the field e_first_name in a survey is represented as [=e_first_name]. This format indicates that the value is not just being referenced, but is being evaluated or calculated at that point in the survey. The use of the equals sign before the field name signifies that the system should process the value dynamically, allowing for any derived or calculated value associated with e_first_name to be displayed during the survey.

In contrast, other formats such as [e_first_name], {e_first_name}, or (e_first_name) do not employ the necessary syntax to indicate evaluation. These options may merely reference the field name without triggering any processing, which means they will not yield the expected output where the actual value of e_first_name is displayed to the respondents.

Utilizing the correct format ensures that the survey collects and displays the data accurately, facilitating a seamless experience for the respondents.
