I think I figured out my problem - now I just need to figure out how to re-write this correctly.

Ok, now, will you figure this out also?

   if not empty(m.lcPrinter)
     select r_invent
	 go top
     BROWSE FOR layout == m.lcLayout  
      scan for layout==m.lcLayout
         =MESSAGEBOX('Test')
         set printer to name (m.lcPrinter)
         report form (m.lcLayout) to printer noconsole nodialog
         set printer TO file '' && want to end a print job
      endscan
   endif

Hint - I only see message test once.

UPDATE. Yes, I fixed it. I think set printer does not even need to be there in the scan loop.
