"Synchronized with list" pairing doesn't stick

Hi All,

I’m trying to pair some stimulus lists, but I’m having trouble getting them to stick. I’m creating the first list, then creating the second list and pairing it with the first. However, when I reopen the second list, the “Synchronize with list” box is blank, rather than displaying the list I selected. Any idea what I’m doing wrong (or what situation(s) produce this problem) and/or how to overcome it?

Are you creating a sublist?

Yes. Sublists of each that match up. It works fine in some cases, but other cases it creates the blank. I haven’t figured out the difference.
