Please help - Array out of range error.

Hi everyone,

I have been giving myself a headache over this for several days and I really need some guidance.

The code in question is a custom indicator that draws 4 lines on a chart. Two for high/low price of the last x number of bars, and two for stops placed a multiple of the ATR below the high/low (ie Trailing ATR stops). 

I create an array[] that stores the values of the high - ATR and Low + ART for each bar. Then I try to create another array[] that stores the ArrayMaximum() of the first array (ie I want the highest (High - ATR) for the last 10 bars).

The code compiles fin but running it gets me  "array out of range in 'BreakOutCI.mq4' (125,19)" in my experts tab. WHICH ARRAY?

I know the bit of code that gets the 'highest (High - ATR) for the last 10 bars' works because I can check it with the Print() function. 

Can anyone can spot what is wrong, and why my array is out of range?

Is this enough of the code, or would all of it be helpful? I didn't want to bombard you with code.

//Function to populate the ATR value and stop arrays
void CalculateATRStops()
{
for(int count=0;count<Bars;count++)
      {
      BuyATRValueArray[count]  = High[count]-(iATR(NULL,PERIOD_CURRENT,ATR_Period,count)*ATR_Multiple);
      SellATRValueArray[count] = Low[count]+(iATR(NULL,PERIOD_CURRENT,ATR_Period,count)*ATR_Multiple);
      }
      
BuyATRValueArray[0] = BuyATRValueArray[1]; 
SellATRValueArray[0] = SellATRValueArray[1];

//--****************** THIS IS WHERE I THINK THE PROBLEM IS *****************
for(int count=0;count<Bars;count++)
   {
//I think problem here V     (this bit works fine) V
   BuyATRStopArray[count] = BuyATRValueArray[ArrayMaximum(BuyATRValueArray,ATR_Stop_Decay,count)];
   SellATRStopArray[count] = SellATRValueArray[ArrayMinimum(SellATRValueArray,ATR_Stop_Decay,count)];
   }
