I have a form with two sets of fields: one for the person who submitted the issue and another for the person to whom this issue is assigned. All participants are in the same Form. The first set captures the person with $USERNAME and the rest get filled with a link. I cannot get a second link set up for the second set of records.
EDIT: Sorry, I have this backwards. It’s the set of records with the $USERNAME that I cannot get to link. I have just tried a duplicate sheet for the lookup without success.
