dvalue

The dvalue tag sets a value to a question or variable. It populates on page load. In the case of visible, respondent-facing questions, respondents can accept the default response and proceed to the next page, or they can choose a different response.

Syntax

dvalue: Value or expression

Examples

Question default value

The below example will have 'mango' pre-selected when the respondent first sees the page. The respondent can then click forward or change the pre-selected answer.

Invisible variable with expression

The below example takes a numeric value given by a respondent and can compute calculations. A new page tag is needed after the initial question as the dvalue variable will compute on page load.

Invisible variable to collect information from invite link

The following example illustrates a common use case for dvalue when a survey is fielding across multiple countries. The 'QCNTRY' variable uses getParm to extract the country parameter from the invite link, indicated by the 'c' parameter, identifying the respondent's country. In this instance, the 'c' parameter corresponds to Great Britain, which is option code 11. Then, dvalue punches that same value/code in 'QCNTRY'.
