Good day. I have multiple worksheets in my workbook. I want to sum the
worksheets by the column called Contract, by quarter. I have made a
quarterly worksheet to capture the figures.

The listing of contract numbers is not constant throughout the worksheets as
new contracts are added as they come up. I think I need a =sumif to specify
the contract number to sum. The columns I need to sum are G through O.

Not sure if I've given you enough info, I've browsed the online
questions/answers and haven't found one that addresses this.
Thanks for your help :)
