Hi Gus, Sorry to hear your back is giving you problems. Hope you are back to normal soon. Pertaining to the DJ software chart, I had such a hard time with it when I first attempted to use it, I used the Excel chart. I love the Excel program and I have not had any problems inserting the blocks so I have not gotten back to working with the software one yet. I appreciate your help and I will try it sometime if I have any spare time. I have four more blocks completed (D1-D4) and will post them soon. Have enjoyed looking at everyone's blocks. Keep the good work up.
