Question: I've spent hours and I can't understand why this is highlighted red and I don't know what my error is.

```
CREATE FUNCTION Student_Section_Count(StudentID INT)

Returns INT

Begin 

DECLARE section_Registred INT;

SET section_Registred= (Select COUNT(DISTINCT Section.ID) as 'Students Registration Count'

FROM Section
Inner Join
Registration on registration.StudentID=Section.ID

Where registration.StudentID=StudentID);

Return Section_Registred;

END$$

Delimiter;

```

It highlights END and Delimiter, as well as INT from Return INT
