Dave: First, my condolences. I respect what you're trying to do for your dad. I'm too far away to be of any help, so, if no one else is able to come in person, you have AT LEAST two alternatives for excellent phone help. The "best" guy is Bruce Palmer of ztherapy, who hangs around here, though you can get him via his website too I'm sure. He'll be the first one to call if he can. Second, call me four oh three six twenty eighty five seventy. I can talk you through it. It's nothing that can't be talked through. And, I know you'll be getting about a hundred offers of help in the next 30 minutes from this group of excellent individuals, so just stayed tuned. Some one will help. Also consider the possibility that its more than just carb adjustment, and there may be little you can do about getting it run for Thursday. You're dad will understand.... God bless Jim
