In the user guide, it says you can use skip patterns with scale responses but NOT with multiple response items. This has always been intentional because a subject could select multiple responses and MediaLab would not know which skip value to use.

There was a bug though (which we just found out about) which would allow you to use skip patterns with multiple response items if and only if the subject was using the keyboard (mouse would not work) and the option with the skip value was the last one chosen. Instead of eliminating this bug, it gave us the idea--why not allow skip patterns for multiple response items so long as only ONE response has been chosen.

So you can do this now--and it will work for both keyboard and mouse. To be super safe, you can combine this with the (r1-1) parameter in order to disallow multiple options from being selected, e.g., (p5,r1-1) for a 5-item multiple response question where one--and only one--option must be selected. That will consequently guarantee your skips to work.
