      2-create a a field (date) with the parameter (

      IF Year([Calendar Date])= [Year]
      [Calendar Date]

      then use this formula

      DATETRUNC('week', [Date] ,DATENAME('weekday',DATE('01/01/'+ STR([Year]))))

      but I having this error


      'Argument 3 to DATETRUNC must be a(n) string'

      so I change the formula

      DATETRUNC('week', [Date] , str(DATENAME('weekday',DATE('01/01/'+ STR([Year])))))

      and again same error

      PLS HELP
