Can't get value!

[helloea]

Why doesn't that get me to value?

Also, no errors in the compiler, but errors in MT5...

void OnStart()
  {
   double Close0[];
   double Low0[];
   CopyClose(Symbol(),PERIOD_CURRENT,0,1,Close0);
   ArraySetAsSeries(Close0,true);

   CopyLow(Symbol(),PERIOD_CURRENT,0,1,Low0);
   ArraySetAsSeries(Low0,true);


   if(Close0[0]>Close0[1] && Low0[0]<Low0[1])
     {
      PlotIndexGetInteger(0,PLOT_COLOR_INDEXES,6);
     }
  }

Perhaps you should read the manual.  OnStart is only for scripts - not for indicators.
