When you create a slider, Storyline automatically creates a number variable to store its value. The value of a variable is available from any slide in the project.
If you want to collect that value and send it to your LMS, you could use JavaScript or another third-party solution.
If you want to stick with just Storyline, you could put the value into a Survey question.
- For example, you could put the slider interaction on a Survey short-answer question.
- Hide the entry field from the user (e.g., cover it up or move it off the slide).
- Use a trigger to put the value of the slider variable into that entry field.
- Then you'll also need to add a Survey Results slide, because that's what tells the program to send the info in the entry field to the LMS.
Or, if that seems too much, I suggest you simply rethink the interaction and use a Survey Likert-scale slide instead. (That will also require a Survey Results slide.)
