Thanks for your help on this one! That definitely made sense. I've run into a couple of other issues, though:
1) In the custom multiple response item, we have 26 options. One option is, if the participant doesn't want to choose any of the other 25 options, they can select "none". I'd like to put in a "skipto" if the participant selects "none", so that they can skip over the next page, which is a ranking activity for the items on the list. (This is because since they selected "none", there aren't any items for them to rank, so they don't need to see this page.) I put the name of the next page into my responses.xls file for this variable, but it didn't seem to work. How can I make this work? Is there conditional logic I need to use?
2) I have a pretty rudimentary "ranking" system right now, but it's not great, and I'd rather use a custom item that will make sure that people don't give the same ranking to more than one item and that they stay within the ranking scale (1-n, n being the number of items they choose in the previous page). Any thoughts on how to redo this?
I'm attaching my code if anyone wants to take a look and make suggestions. Thanks!
