Greetings,

I need assistance in creating a formula that will allow me to keep columns that accumulate daily.

Example:
In one workbook I get the totals from our daily business. Then on a separate workbook I create a weekly total and on a third workbook I have the monthly. I would like to have the weekly and the monthly update automatically based on the daily totals but I cannot figure out the formula that will allow me to do this.

Please help me

Thank you
