RE: [amibroker] Bars Since Question/Problem, Please Help

I have been trying to use "Bars Since" In an exploration that 
calculates the number of bars since the price has crossed above or 
below the indicator(s), When I run the exploration the "buysignal" 
and "sellsignal" columns are empty. I have tried a number of ways 
with no success.  Am I missing something or is there a better way to 
do this? Any help will be appreciated.  I have provided the code 
below. 



PCLG=PRSI(C,100,150);
Plot(PCLG,"",colorBrightGreen,styleThick);

PCS2=PRSI(C,3,3);
psp=Param("psp",5,2,500,1);
PST=(t3(PCS2,psp,1.0));
Plot(pst,"",colorBlue,styleThick);

PCLR=PRSI(C,100,30);
psr=Param("psr",10,2,500,1);
PSRL=(t3(PCLR,psr,0.94));
Plot(psrl,"",colorRed,styleThick);

PCS=PRSI(C,43,50);
PCSW=(pcs+pcs2)/2;
psw=Param("psw",7,2,500,1);
PSWL=(t3(pcsw,psw,0.94));
Plot(pswl,"",colorWhite,styleThick);

LR1=LinearReg(C,23);
Plot(Lr1,"",colorYellow,styleThick+styleNoLabel);

PCLR1=PRSI(C,200,230);
psr1=Param("psr1",7,2,500,1);
PSRL1=(t3(PCLR1,psr1,0.94));
Plot(psrl1,"",colorBlack,styleThick);


bls=BarsSince(Cross(psrl1, H ));
bgs=BarsSince( pslr1 > H );
bus=BarsSince( pst > H );
res=BarsSince( psr1 > H );
whs=BarsSince( pswl > H );
yes=BarsSince( Lr1 > H );
Sellsig=(bls+bgs+bus+res+whs+yes);

blb=BarsSince( psrl1 < H );
bgb=BarsSince( pclg < H );
bub=BarsSince( pst < H );
reb=BarsSince( psr1 < H );
whb=BarsSince( pswl < H );
yeb=BarsSince( Lr1 < H );
Buysig=(blb+bgb+bub+reb+whb+yeb);


Filter=1;
Sell=(Sellsig<30);
PlotShapes(shapeDownArrow*Sell,colorRed);
GraphXSpace=5;
AddColumn(Buysig,"BuySignal");
AddColumn(Sellsig,"SellSignal");
