[amibroker] Help to arrange Formula

[trocito1997]

Hi,

I am trying to use this formula but had error:

Error 30 Sytax Error, Do you could help me ,


The code is:

_SECTION_BEGIN("Chart Settings");
   SetChartOptions(0,chartShowArrows|chartShowDates);
   SetChartBkColor(ParamColor("Outer Panel",1));
   SetChartBkGradientFill(ParamColor("Upper Chart",1),ParamColor("Lower 
Chart",23));
   GraphXSpace=Param("GraphXSpace",10,0,100,1);
   dec = (Param("Decimals",2,0,7,1)/10)+1;
   bi = BarIndex();
   Lbi = LastValue(BarIndex());
   sbi = SelectedValue(bi);
   x1= BarCount-1;
SetBarFillColor (IIf(C>O,19,IIf(C<O,24,42))); 
Plot(C,"",IIf(C>O,51,IIf(C<O,33,55)),64); 



Thanks
