multiple inner join error

[virkof]

Hi everyone, I am trying to do a query with 7 different tables by using the inner joint. When I run it it sais

ERROR at line 15:
ORA-00905: missing keyword

Any ideas what it could be?

SELECT 	FUNCTIONS.FUN_NAME, FUNCTIONS.FUN_ID, FUNCTIONS.FUN_NAME, 
	EQUIPMENTS_FUNCTIONS.EQUIP_DESCRIPTION, HIRE_EQUIPMENTS.HEQUIP_DESCRIPTION,
	STAFFS.EMP_TITTLE
FROM	FUNCTIONS,EQUIPMENTS_FUNCTIONS,FUNCTIONS_HIRE_EQUIPMENTS,FUNCTIONS_STAFFS
INNER JOIN 	
	EQUIPMENTS_FUNCTIONS ON  FUNCTIONS.FUN_ID = EQUIPMENTS_FUNCTIONS.FUN_ID JOIN 
INNER JOIN
	EQUIPMENTS_FUNCTIONS ON EQUIPMENTS_ID.EQUIP_ID = EQUIPMENTS.EQUIP_ID
INNER JOIN	
	FUNCTIONS_HIRE_EQUIPMENTS ON FUNCTIONS.FUN_ID = FUNCTIONS_HIRE_EQUIPMENTS.FUN_ID
INNER JOIN
	FUNCTIONS_STAFFS ON FUNCTIONS.FUN_ID = FUNCTIONS_STAFFS.FUN_ID
INNER JOIN
	STAFFS ON FUNCTIONS_STAFFS.EMP_ID = STAFFS.EMP_ID 
WHERE FUNCTIONS.FUN_ID = 'F20031235';
