I need to continually add numbers to one cell and to have it total in the same cell. For example: Each payday I need to add gross amount of the paycheck to March's income so if one is paid $200. on March 1st, $100. on March 8th, $500. on 15th and etc, I want to have one cell total $800. instead 4 (or 5) seperate cells. Thank you for any help and assistance.
