Currently my data looks like this where the running total is calculated using the formula in C2 is

Code:

`=SUM($B$2:B2)`

This works fine until I reach row 14. Here I would like the formula to 'restart' so it would be

Code:

`=SUM($B$14:B14)`

Is there anyway I can achive this 'restart' by counting the number of rows so I don't have to manually update the formula as I go?

I know it is possible to use the function in a PivotTable but that's not the solution I'm looking for.
