Im stuck with this, I hope someone can help me with this:

```
SELECT max(SELECT count(TO_CHAR(hire_date, 'DAY')) 
           FROM employees 
           GROUP BY TO_CHAR(hire_date, 'DAY')) 
FROM employees;

           *
ERROR at line 1:
ORA-00936: missing expression

```

The output of the subquery looks like that: 

```
TO_CHAR(HIRE_DATE,'DAY')         COUNT(TO_CHAR(HIRE_DATE,'DAY'))
---------------------------------------- -------------------------------
THURSDAY                                   3
SATURDAY                                   3
WEDNESDAY                                  4
MONDAY                                     1
SUNDAY                                     3
TUESDAY                                    6

```
