Hi Cameron,

I'll have to do some testing on my end, but I think because the lookup is specific to the LSID, that could create some issues when re-establishing lookups since LSIDs end up being unique in each respective LabKey instance.

Just curious, does the list need the actual LSID value to be displayed like in attachment number 5 (without the < > symbols) or does it need to display in the same format as it shows in attachment number 7, repeating the same participantId value?

I think there may be a way to use XML Metadata code instead of the Lookup feature in the UI, but that would depend on your answer to the question above.

Regards,

Jon
