RPL loop data within loop data

I am having trouble with an RPL loop inside an RPL loop.

My setup is as follows:

SQL view campaign_dist (filters only members of this particular campaign)

Contains CUSTOMER_ID

SQL view campaign_members_distinct (contains deduped/distinct list of campaign members)

Contains CUSTOMER_ID, POLICY_NUMBER, MEMBER_NAME, PRODUCT_NAME, PRODUCT_TYPE

One Customer ID can match to many POLICY_NUMBERs

SQL view campaign_policy_lookup (contains all data)

Contains all data, not deduped

Each member might have multiple policies, so this requires us to loop the policy data under the a loop of members. This way we end up with a header for each member, and a listing of the policy information below their name
