I'm Having Trouble With Doing Multiple Joins

Here is what I am currently doing:
********************************************
SELECT Hours.Hours, Hours.Comments
FROM Hours INNER JOIN Employee
ON Employee.UserID = Hours.UserID
INNER JOIN Task
ON Hours.TaskID = Task.TaskID
INNER JOIN Project
ON Hours.ProjID = Project.ProjID
WHERE Hours.Date <= EndDate
AND Hours.Date >= StartDate
AND Hours.Date <= EndDate;
********************************************
Am I doing something wrong here?
Any help would be greatly appreciated!
