We're doing essentially the same thing with the NDA question created as an access gate requiring approval before advancing to the RFP.
One challenge I've had is preventing visibility to the event content until the access gate is met. It seems to hide Questions but not Requirements. Frankly I want to hide the requirements b/c they contain the confidential information I need the NDA for.
The directions in the PD state:
"If you are designing your event with access gate questions, you can hide content from participants until they have cleared the access gate. Set Visible to Participants to Yes, after access gate is clearedfor all content items you want to hide until participants are allowed into the event. If you have access gate questions, but no content is set to be hidden, then participants can see the event content even if they have not cleared the access gate."
I don't see an option to allow visibility after gate is cleared; just Yes/No to visible to participants. Making it more confusing, the information icon displays a similar message as the PD.
(We've created a visibility condition at the section level and tied it to a confirmation question high in the event content. Once bidders pass the gate they then have to indicate acceptance to terms for the RFP before they can see the requirements. Since questions are hidden, this 'secondary gate' meets our need, albeit I'm sure there is a better way)
