Engine.AddAnchor()

Santiago

Hello.
I want to do the following:

procedure txtOPsAdmOnBeforePrint (Sender: TfrxComponent);
var
? ?  field, name, anchor: string;
begin
? ?  //Engine.AddAnchor(<SeccAdministrativaPaginado."Identifier">.);
? ?  Field: = TfrxMemoView (Sender) .DataField;
? ?  Name: = TfrxMemoView (Sender) .DataSet.UserName;
? ?  Anchor: = <name + '."' + field + '"'>;
? ?  // ShowMessage ('Anchor' + anchor);
? ?  Engine.AddAnchor (anchor);
end;

I get the following error:

The following error(s) have ocurred:

Unknown variable or datafield name + '."' + field + '"'
