You miss the HAVING CLAUSE because of the COUNT...

SELECT
Employees.ID, Employees.FirstName,
Employees.LastName, Employees.Department,
COUNT(ReportRequests.ID) AS Ctr
FROM
Employees, ReportRequests
WHERE
Employees.ID = ReportRequests.EmpID
GROUP BY
Employees.ID, Employees.FirstName,
Employees.LastName,
Employees.Department
HAVING
COUNT(ReportRequests.ID) > 1
