firstday = ValueWhen( Cum(1)==1, DayOfWeek() );
numweeks = IIf(LastValue(DayOfWeek())==firstday,
LastValue(Cum(DayOfWeek()==firstday)),LastValue(Cum(DayOfWeek()
==firstday))+1
);

numweek = IIf(firstday==1, Cum( DayOfWeek() < Ref(DayOfWeek(),-1) ),
IIf(firstday>1, Cum( DayOfWeek() < Ref(DayOfWeek(),-1) )+1 , 0 ));
numweek = IIf(IsEmpty(numweek),1,numweek);

firstbar = LastValue(Cum(1))-LastValue(numweek)+1;
dayRef =  5-LastValue(DayOfWeek()) + 4*( Cum(1) - LastValue(Cum(1)) );
xxx =  Min(0,5-LastValue(DayOfWeek()) + 4*( Cum(1) - LastValue(Cum
(1)) ));

wo = IIf(IsEmpty( Ref(DayOfWeek(),-DayOfWeek()) ),
ValueWhen(DayOfWeek()==firstday,O), ValueWhen(DayOfWeek()==1,O ) );
wh = HHV(H,Min(DayOfWeek(),5));
wl = LLV(L,Min(DayOfWeek(),5));
wc = C;

weeko =Ref(wo,xxx);
weekh = Ref(wh,xxx);
weekl = Ref(wl,xxx);
weekc = Ref(wc,xxx);
