Thanks for the feedback.
I made a silly (beginners!) error.
I defined EKT_order and EKT_orderby by like this: _
/Public EKT_order as ////New //String
///Public EKT_orderby as String
//and called a Procedure
/MakeOrderType(EKT order , ///EKT orderby,/, fld , Column)
//Public Procedure MakeOrderType(arorder As String, arordorb As
String, fld As String, clmn As Byte)
/Shame on me, cost me almost two days seeking the error. I just forgot
