Update the main Tab

Hello all,

I have all the users in main tab and they have their own tabs, when they update their values in columns that should reflect in the main tab . How do I do this, any help is appreciated, I am kinda new to vba so need help..

Thanks a lot..

Debbi Tab Total SubTotal Rev


If debbi changes her Total, subTotal and Rev then it should reflect in main tab under her name...
