Nested NL functions

Hi,

I was hoping someone could tell me why this formula isn't working…

=NL("Count","Prod. Order Routing Line",,"No.",$E$3,"Routing Status","Finished","Ending Date","=NL(,""Capacity Ledger Entry"",""Posting Date"",""Order No."",NF(,""Prod. Order No.""),""Operation No."",NF(,""Operation No.""),""-Posting Date"",""*"")")

The part that's not working is the nested NL statement after the "Ending Date" parameter.

Any questions let me know.

Thanks,
