my workbook contains 13 sheets - 1 for each month of the year + a summary
sheet. Each sheet has 21 line items which contain a Total$Spent cell. I need
to take the value in the Total$Spent cell for each month and add them to
arrive at a Y-T-D total for each line item on the summary sheet.

Can you tell me how to build this formula?
