Hi all,

For part of a project, we are asking participants to nominate two members of their family to participate in a Stage 2. Unique codes for these two family members will be automatically generated and stored as two different embedded data (i.e., Code_1 & Code_2). These codes would be saved into a new contact list and an authenticator will be set up for the Stage 2 link so that ONLY the generated codes can have access to Stage 2.

The problem

The two generated codes will be saved in two different embedded data fields in the initial survey. However, in order to save the codes into the contact list under the same “code” field (i.e., External Data Reference etc.), they will need to be first saved under the same name to be saved under the same column in the contact list, so that the authenticator can pick them up.

However, if I were to set it up so that Code_1 and Code_2 is saved under the same third embedded data field (i.e., ExternalDataReference), one will override the other, and only one will be saved in the contact list.

My question

Is it therefore possible to have the two generated codes saved under the same variable name so that they are both stored in the contact list to be used in the authenticator during Part 2 of the survey?

Note – I know it could be possible to set up a loop to allow participants to nominate as many people as they want, but ideally I wanted to stick with 2 for now to make it more manageable for the team. Also, I wanted to make it all on one survey rather than a loop in case people are inviting twins as this is a key part of some of the research.
