Working days formula and Crystal 7 - is it possible?

Question

Hi folks,
Really hope someone can help, I'm struggling with writing a report that needs to show the difference between two dates in working days. I've found the same formula posted here several times but cannot get it to return a logical value in my report. I'm wondering if that might be because I'm using an older version of Crystal? The formula in question is this one:
//Main formulaWhileReadingRecords;Local DateVar Start := ({PPV_COMPLAINTSEH.DTRECD});   Local DateVar End := ({PPV_COMPLAINTSEH.ACTCMPLTD}); Local NumberVar Weeks; Local NumberVar Days; Local Numbervar Hol;DateVar Array Holidays;
Weeks:= (Truncate (End - dayofWeek(End) + 1 - (Start - dayofWeek(Start) + 1)) /7 ) * 5;Days := DayOfWeek(End) - DayOfWeek(Start) + 1 + (if DayOfWeek(Start) = 1 then -1 else 0)  + (if DayOfWeek(End) = 7 then -1 else 0);  
Local NumberVar i;For i := 1 to Count (Holidays)do (if DayOfWeek ( Holidays[i] ) in 2 to 6 and      Holidays[i] in start to end then Hol:=Hol+1 );
Has anyone come across an alternative way of doing this, or have any ideas why this formula is not working in my report? Any advice would be much appreciated,
Regards,
Tim

You set up a Running Total.  Drag the filed you want Summed, Select Sum as the operation if that is not the default.
Just below that you weill see Radio Buttons that say For Every Record, On Change of Group, On Change of Field, Use a Formula, etc - click the one that says Use a Formula.  The Blue Bos to its right will turn Red, click on it, this is where you put your formula: NOT(DATEPART('w',{table.date}) IN [6,7])
Save that, then just decide if you want it reset on a Change of Group, or Never (Grand Total).  Give it a name and put it on your report.
