Translate Sumifs logic to a working Excel formula

[caabdul]

Hi

I have following logic but can't create a sumifs Formula.

D1 Logic=Sumifs(Sum ColumnS IF 
                                        (
                                         the value in cell A1 matches with value in columnN AND 
                                         the value in columnM is "pleted " AND 
                                        (the value in ColumnP is nothing OR "" OR less than or Equal to 200) AND
                                        the value in columnR is (LessThan or EqualTo 6 OR Greater than 8)
                                         )

I have made following formula but it is not working;

=SUMIFS(S:S,N:N,A1,M:M,"pleted ",P:P,"<="&200,R:R,OR("<="&6,">"&8))

Any clue?
