Questions

Questions section can contain question text together with Data Elements.

Data Elements are taken from column names of the Data File. If the column headers do not match the variables within the Task design, a warning message is displayed alerting you which column names need to be remapped. See the Upload Data topic for details.

Data Elements have the following template: ${question.data['data_element_name']}

In the Question section, you can perform the following actions:

• type Rich Text
• type Data Elements
• delete Data Elements

In the Side Panel, you can only insert Data Elements at the current cursor position.

Do not type or paste Data Elements into Title or Instructions sections – the Preview will not be accessible.

Dynamic Expressions in Answer Options

Select One, Select Multi, Check One, and Check Multi answer types support dynamic expressions in options of the following type:

${question.data.A}=${question.data.B}
${question.data.A}=1; 2=${question.data.A}
PREFIX${question.data.A}SUFFIX${question.data.B}=${question.data.C} // PREFIX, SUFFIX - any strings

In the example above, A and B are the column names from input Data file. On Preview and Endpoints these expressions are substituted by values from corresponding columns.

Dynamic expressions are useful in case these answers should have multiple values – no need to enter them manually.

For example:

Input File or Data Store	What Worker sees	What Worker selects	Result
Title: Yahoo, Facebook; URL: http://yahoo.com , http://google.com	Yahoo, Facebook	Yahoo	http://yahoo.com

To use these columns in Answers, add the following dynamic expressions to the Options list:

The following figure displays dynamic expressions in Design Task and Preview:
