Lectora Basics: About Question Variables
Quite often, we get questions from our Lectora® users wondering how they can provide some kind of customized behavior based on a learner’s response to a question, such as showing a checkmark or an X next to each option of a drag and drop or matching question. And most often, the answer involves querying the contents of the question object’s associated variable. Every time you create a question object, an associated reserved variable is automatically created. You can see these on the Properties ribbon for the question and on the Reserved tab of the Variable Manager.
But how can you tell what is inside of those variables at any given time? The easiest way to see the contents of a variable is to run the page containing the question in Debug Mode. You will find this on the View ribbon.
When you run a page in Debug Mode, an external pop-up window appears that tells you what is happening behind the scenes. The Debug window will display every READ and every SAVE that happens with the variables on the current page, and also shows the current value of those variables within [brackets].
The initial value for all question types is null or empty, meaning the learner has not yet attempted to answer the question. But once the learner has interacted with the question, the value of its associated variable will change. The format of the value varies by question type. The table below explains the formats for the 12 different question types available in Lectora.
Tables can't be imported directly. Please insert an image of your table which can be found here.

Now that you know what to expect to find inside of the question variables and how to see the contents of them for yourself running under Debug Mode, you can set up actions with conditions that query the contents of a question’s variable to trigger some desired behavior. In the example below, the action is set up to show a check mark if Question_0002 contains 1L-1R for an option of a Matching question if the condition is true. If the condition is false, the action shows an X instead.
