This requires a custom item because MediaLab typically presents 1 item at a time. You can check out the Custom Items section of the user's guide to get a feel for how it works. There are also posted samples around on these forums. I could also help point you in a direction if you would like to describe the scales you'd like to use. E.g., 1 to 7 Likert. Continuous slider from 0 to 100, etc.
