I have a problem with relations on Neo4j. I have 3 files with the .csv extension to be loaded into Neo4j. The first two files are nodes that I already and successful created. The files are: forum\_0.csv & person\_0.csv and they got this headers:

idForum|titleForum|creationDateForum (forum\_0.csv)

idPerson|firstNamePerson|lastNamePerson| ... (person\_0.csv)

I successful create the two nodes but now I need to create a relation between these nodes. For that I need to load the third file, forum\_hasMember\_person\_0.csv 
(and this file got this header:
idForum|idPerson|joinDateFHMP )

and my problem is at this point. I load the third file with this code:

```
USING PERIODIC COMMIT
LOAD CSV WITH HEADERS
FROM ".../forum_has_Member_person_0.csv" AS row
FIELDTERMINATOR "|"
MATCH (forum:Forum(idForum: row.idForum))
MATCH (person:Person(idPerson: row.idPerson))
MERGE (forum)-[:FOR_HASMEMBER_PRS]->(person);

```

How can I create the FOR\_HASMEMBER\_PRS relation with "joinDateFHMP" property?
It's the only thing left on the relationship creation. How can I solve this?
