Catalog Item - Multiple People

[Lloyd700]

Hello all.  I have a catalog item that I'm not sure how to set up.  There are two sets of fields to fill out on the form.  The basic gist of the flow is:

Step 1 - User 1 fills out 'Set 1' of questions

Step 2 - That set of information goes off for approval to user 2

Step 3 - User 3 gets notified of the approval, which they then need to fill out the 'Set 2' questions

I originally created all of the questions on the form, and hid 'Set 2', assuming that 'User 3' would be able to see them on the RITM that was created upon the form being filled out, but they are hidden there also.  I also tried to define a behavior for the fields to show up when the request has been approved, but couldn't figure that out either.

What would be the best way to go about this?

Filling in the 'Set 2' questions on the RITM is just fine.

At this point, the biggest issue I'm having is, I've created 'Set 1' and 'Set 2' in "Two-Column Containers".  In the Catalog Builder UI, it lets me assign behaviors to the containers, but as soon as I "Review and Submit" those behaviors go away.

Is there something special I need to do to add behaviors to a container full of questions, rather than to the questions themselves?
