Quarter to Date Figures

[#1]

Hi,

i am currently struggling to form a QTD figure in my P&L.

I have created YTD and PTD no problem with the following code. I have used variables that are visible here to select max years and ,ax periods that are complete:

YTDActual:

Sum({<FY={$(vMaxYear_CompletePeriod)},Period={'<=$(vMaxPeriod_CompleteFYPeriod)'},>} Amount)

PTD Actual:

Sum({<FY={$(vMaxYear_CompletePeriod)},Period={$(vMaxPeriod_CompleteFYPeriod)}>} Amount)

As you can see the only difference is the summing sign in front of my second variable to make it add all present values and give me a YTD figure.

How could i alter that code to make Quarterly, ie when you view QTD you will first three months summed (1-2 inclusive) and then the next QTD you will the following three months summed (4-6 inclusive).......

thanks,

James
