Marc,
Can you try this: (I don't know if I figured out your relationship right)

SELECT virtual.*, iif(V_Weight=0,0,v_Value/v_weight) as price;
 FROM  Stock INNER JOIN Virtual;
    INNER JOIN Sale ;
   ON  Stock.stk_Parcel = Virtual.V_Stock ;
   ON  Stock.docnr = Sale.docnr;
 WHERE V_Box= cKey;
  AND V_Status= hStk_Sale;
  into cursor glSold

and yes, make sure that all tables are open before sql statement executes. (just in case)
