There seems to be a server problem on the Pace DNA site. I uploaded the group 3 chart to two other servers, one at Webster university and the other on the Pace Network . It works fine there. I am in the middle of a change of location right now, but if it can't be solved at our server end, I can set the charts up on the Pace Network and link from the DNA site and it will work just fine but I can't get at that for several days. Meantime hopefully the server problem can be solved. Roy Johnson
