I have two tables as follows:
table_parent with columns ID (text - uniqueID), datecreated (datetime), link_ID (text, contains appsheet formula [ID]),description (text)
table_child with columns ID (text - uniqueID), datecreated (datetime), description (text), quantity (number), link_ID (ref to table_parent)
When I add a row to the parent and add couple rows to the table through the related form view, the trns_ID field of child table remains empty. Thus I can not maintain the link between the parent and child records.
