1. Why do you need the validation if the data for this question is inputted by URL?
I don't "really" need this second round of validation. As you point out, in theory this answer has already been validated when input on the original question (survey A) and passed via end URL to survey B. My intent with re-validating the hidden field is to prevent population if the user has messed with the URL params.

2. Does it work fine if the question is not hidden?
Yes, validates correctly if the question is not hidden.
This is not a huge deal, as it is unlikely that the users of my survey will intentionally modify the url, but you never know.
