[Richard]

Question ... can you make a composite of stocks in a "Watch List".  I've tried 
but keep getting an error message. It works fine with Industry groups (see 
below) but error comes up with watch list.watch list 9 is one of SolarEnergy 
stocks.

//sym = "~" + IndustryID(1);
sym = "~" + watchlistID(9);
AddToComposite( L, sym,"L",1+2+8+16);
AddToComposite( O, sym,"O",1+2+8+16 );
AddToComposite( H, sym,"H",1+2+8+16 );
AddToComposite( C, sym,"C",1+2+8+16 );
AddToComposite( V, sym, "V",1+2+8+16);
