setvalue populates a given survey field with a particular value. It is most commonly used for coding of skipped fields or populated derived fields and can be defined as a standalone widget or element decorator.
Syntax
# Setting a value
setvalue
question: Question ID
value: Value or expression
# Setting a single option value to checkbox, preserving any existing data
setvalue
question: Question ID
option: Option ID or expression
value: 1 or 0
# Setting multiple values to a checkbox, overwriting all existing data
setvalue
question: Question ID
value: [Option 1, Option 2, etc.]
# Setting a value inline as an element decorator
1. Some question
type: radio
1. Set Q2 to 1 {set question: Q2 value: 1 }
2. Set Q2 to 2 {set question: Q2 value: 2 }
Caution! Using the value tag without the option tag on a checkbox question will overwrite any existing checked options.

Examples

Note: As an alternative to the above example, it is possible to apply the autocode tag directly to a follow up question when only a single option has been selected in a previous question.
Perl concatenate in sum-to-100 table
Combine split table data
Note: The two vertical pipes (||) in the set value widget's value tag above indicate an "OR". There are instances where you may need to use two forward slashes (//); for example, when piping forward the response code "0".
