Data between two dates

Hello

Here is my code :

WITH 
MEMBER [MEASURES].[TEST]  -- CALCUL DU NOMBRE D'OPC ATTRIBUE A L'EQUIPE
AS 
[Axe_ORGANISATION].[ID_COLLABORATEUR].members.count
SELECT NON EMPTY { [MEASURES].[TEST] } ON COLUMNS, NON EMPTY { ([Axe_ORGANISATION].[PROFIL].[PROFIL].ALLMEMBERS 
*[Axe_ORGANISATION].[NOM_PLATEAU].[NOM_PLATEAU].ALLMEMBERS
* [Axe_ORGANISATION].[NOM_UNITE].[NOM_UNITE].ALLMEMBERS
*  [Axe_ORGANISATION].[ID_COLLABORATEUR].[ID_COLLABORATEUR].ALLMEMBERS  
* [Axe_ORGANISATION].[NOM_EQUIPE].[NOM_EQUIPE].ALLMEMBERS ) } 
DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS 
FROM ( SELECT (  [Axe_ORGANISATION].[PROFIL].&[Conseiller Client] ) ON COLUMNS 
FROM [PVC_Reporting]) 
(where format([Axe_ORGANISATION].[DATE AFFECTATION DEB].[DATE AFFECTATION DEB], "yyyyMM") <@AxeTempsMOISANNEE 
and Axe_ORGANISATION].[DATE AFFECTATION FIN].[DATE AFFECTATION FIN], "yyyyMM")  >@AxeTempsMOISANNEE)

As a parameter I receve a string of a date in format yyyMM. I need to filter data based on date begin and end of and employee.
