I need help figuring out a formula to orginize my patients information. I have 24 patients that have hemoglobins (these numbers are not percents). I need to calculate the percentage that is <10, the % of pt's 11-12, and the % of pt's that are >13. I have to do this each month and I thought it would be great to do it this way! Can anyone help with this? I need it by Tuesday!
