Help Plot Arrows

Hi Everybody,
I am new to write AFL codes.Have been trying unsuccessfully to plot shapes in the following code.It is filtering the stocks correctly but arrows are not showing:

TimeFrameSet(3600);
for(x=0;x<BarCount;x=x+7)
Filter=GapUp();
PlotShapes(IIf(GapUp(),shapeUpArrow,shapeNone),colorGreen,0,0,-12);

Can someone help please !

thanks

the code is nonsense.

Hello Detwo,

Thanks for replying.Yes I am just trying out newly.I must have made some mistake.The blue part works fine in finding gapups in hrly charts.I am not sure of the plotShapes part.Can you suggest any correction?

thanks
