Saving row.file_name as relationship label

Hey! I am trying to run this program:

LOAD CSV WITH HEADERS FROM 'file:///HHXURBRRL.csv' AS row
WITH row
WHERE row.HHX IS NOT NULL AND row.URBRRL IS NOT NULLMERGE (hhx:HHX {data: row.HHX})
MERGE (urbrl:URBRRL)MERGE (hhx)-[:\{row.URBRRL}\]->(urbrl);

​

CSV FILE

From this MERGE (hhx)-[:{row.URBRRL}]->(urbrl); I want the relationship label to be 1,2,4, with these actual data in the URBRRL row. How do I do this? Thanks for helping!
