Sum Running Total in Crystal Report - crystal-reports

Question

I created a running total for my report, we will named it RT1. Now i created again another running total to get the sum of RT1 but i get the wrong answer. Any advice on how to correctly do this?
I have this formula in my first Running Total
//Formula1
#SpTotalReset
WhilePrintingRecords;
numbervar sp := 0;
//I placed it in my GroupHeader Date
//Formula2
#SpRunningTotal
WhilePrintingRecords;
numbervar sp;
sp := sp + {Sec/Pc};
//I placed it in my Details
//Formula3
#SpTotalDisplay
WhilePrintingRecords;
numbervar sp;
//I placed it in my GroupFooter Date
This is the formulas of my second running total
//Formula1
#MoTotalReset
WhilePrintingRecords;
numbervar mo := 0;
//I placed it in my GroupHeader Date
//Formula2
#MoRunningTotal
WhilePrintingRecords;
numbervar mo;
mo := mo + {#SpTotalDisplay};
//I placed it in my GroupFooter Date beside #SpTotalDisplay
//Formula3
#MoTotalDisplay
WhilePrintingRecords;
numbervar mo;
//I placed it in my GroupFooter Name

Answer 1

Change like this:
#MoTotalReset
WhilePrintingRecords;
Shared numbervar mo := 0;
//I placed it in my GroupHeader Name
And apply shared for all formulas. This should work.
