This my simplified script: Sub SomeOtherSub(Stattyp As String) 'Daty and the other variables are defined here CatSubProduktAreakum(Stattyp, Daty + UBound(SubCategories) + 2) End Sub Sub CatSubProduktAreakum(Stattyp As String, starty As Integer) 'some stuff End Sub The call of CatSubProduktAreakum is marked red as a "syntax error".
