Select Statement Returns No Results

I am using the following conditional select statement but it returns no results.


Declare @DepartmentName as varchar
Set @DepartmentName = null
Declare @status as bigint
Set @status = 4
IF (@DepartmentName = null) BEGIN

SELECT CallNumber AS [Call Number], Problem, Solution, Note
FROM AdminView
WHERE (Status = @status)
ORDER BY CallLoggedDT
END
ELSE IF (@DepartmentName <> null) Begin

SELECT CallNumber AS [Call Number], Problem, Solution, Note
FROM dbo.AdminView
WHERE (Status = @status) AND
(DepartmentName = @DepartmentName)
ORDER BY CallLoggedDT
end



when i run the 2nd half by itself it tells me to declare @status but not @departmentname. whats going on???
