Ah. Was actually looking at the same thing when you sent this :-)  
Your advice is close but the wrong direction. If I do a factor[]: .01  
then I'm golden. Thanks so much! I guess this should have been  
obvious but it's interesting to me how many other people had the same  
question in various other forums but never posted a final resolution.  
Hopefully this will help someone down the road with a little
