Here is a pic of my sheet. I'm trying to find a way to identify a specific CHILDREN row. I thought that using JOIN to bring together the columns that are unique would give me something to refer to to identify a specific CHILDREN row. I'm trying to JOIN the PL##### with the GRANDCHILD under Deliverable Name and Assets. The result I'm looking for is:
PL25148,Request Received and PL25148,Copyediting
However, my JOIN formula isn't working. Any thoughts?
