Please help this newie... :)
I'm trying to get the code below to display either the EMA with price,
OR the crossover signals, choice being through the Parameters (Ctrl-R)
function. It doesn't seem to work here, and it plots both instead.
Any idea what I'm doing wrong?

Title = "EMA/breakout signals";
pds = Param("EMA periods",21,1,252,1);
x = Param("Op=1 Hi=2 Lo=3 Cl=4 Vol=5",4,1,5,1);
shift = 1+Param("EMA vertical shift %",0,-100,100,0.01)/100;
display = Param("EMA=1, Signals=2",1,1,2,1);
x = IIf(x==1,O,IIf(x==1,H,IIf(x==1,L,IIf(x==1,V,C))));
prds = IIf(Cum(x!=-101)<pds,Cum(x!=-101),pds);
EMA1 = AMA(x,2/(prds+1))*shift;
signals = Cross(x,EMA1)+Cross(EMA1,x)*-1;
IIf(display=2,
Plot(0,"",colorBlue,styleLine),
Plot(Close,"",1,128));
IIf(display=2,
Plot(signals,"EMA signals",colorRed,styleLine),
Plot(EMA1,"EMA",colorRed,styleLine));
