Totaling multiple running totals on separate sheets

[ashncg]

Hello,
I have 6 sheets in a workbook. On 5 of the sheets, there is a running total in column AK. On the 6th sheet, I need a running total of all 5 of these running totals. Each of the 5 running totals will be added to and updated at different times (each of the five are independent of each other, and I'll need the running total on the 6th sheet to update each time any of the 5 is updated). Is this possible?

Something like this?

Almost, but there is only one column in the running total on each of the 5 sheets. So there is a column where numbers are being entered into, and then there is a running total of that column on each one. Then, on the 6th, I need the formula to total up all of those single running total columns.

Do you have a sample workbook you could attach?

Sheets 1-3 have a column of data and then a column that's a running total of that data. On sheet 4, I need a running total of all 3 running totals, that will update when each one is updated, and they won't all be updated at the same time, because each one is independent.
