I am using a dual-scale array with dropboxes, and for each subquestion, I want the second scale dropbox to appear grayed out (or at least the answer options inside it to be blank) until an answer has been selected on the first subscale.

A simpler way to ask this question would be: "Can the second scale answer options in a dual-scale array be dynamically tailored based on the first-scale answer selected for each subquestion?"

Thanks!

Eureka! I found the exact answer I needed in this same forum:

Sorry about not having looked hard enough for it before posting...

I guess the same script that's provided in the thread above can also be modified, so instead of filtering the second scale based on the first-scale answers, other logic could be embedded in the second scale based on the current row in the array.

Even more wonderful would be:

1. For EM to have a variable similar to "this" or "self" that referenced the answers in the current array row. That would solve a lot of logic coding issues around answer options.

2. For answer options to support relevance expressions directly, the way it's done for subquestions.

Cheers to all!
