Importing data from JSON - neo4j

Question

I'm facing an issue importing a JSON file using the apoc.load.json procedure.
The expected relationship I'm trying to capture:
University --child--> Class --child--> Student
Output:
Neo.ClientError.Statement.SyntaxError: Variable `value` not defined (line 1, column 8 (offset: 7))
"UNWIND value.university AS university"
Here is the performed command sequence:
CALL apoc.load.json("FILE:///C:/tmp/input.json") YIELD value
UNWIND value.university AS university
UNWIND university.class AS class
UNWIND class.student AS student
MERGE (u:UniversityCategory {name:university.name})
MERGE (c:ClassCategory {name:class.name})
MERGE (s:StudentCategory {instr:student.name})
ON CREATE SET i.ID = instructions.ID
ON CREATE SET i.GPA = instructions.GPA
MERGE (u)-[:CHILD]->(c)
MERGE (c)-[:CHILD]->(s)
Here is the JSON file structure:
{
"university": [{
"name": "universityA",
"class": [{
"name": "class_1",
"student": [{
"name": "student_1",
"ID": "1234",
"GPA": "3.8"
},
{
"name": "student_2",
"ID": "12345",
"GPA": "3.4"
}
]
},
{
"name": "class_2",
"student": [{
"name": "student_3",
"ID": "14",
"GPA": "3.0"
}]
}
]
}]
}
My apoc.load.json command appears to work because I see the structured JSON file in the browser window. The next steps are suspect but I think I'm close to defining the relationships.

Resolved my issue.
The commands I expressed above are all correct but the load.apoc.json command has to be run in the SAME query as the rest versus sequentially.
