You are obviously Technology Challenged. Don’t expect People on this forum to solve your problem. Go to a community College or a Junior College and take a course or go to your local SCORE office for help. The other solution is to sit down with a piece of paper and a pencil and do the simple math. You’re obviously not ready to use a computer to do what you want to do. GET SOME OUTSIDE HELP, take a course, buy a EXCEL FOR DUMMIES book before you get on here and expect us to fill in the blanks for your lack of knowledge.
