Main Chart Disappears -- code included

Hey everyone:  I'm wrote a function that evaluates Pearson Coefficient.  I tested the formula and it's 100% correct with results.  I'm trying to calculate the coefficient on Close and the % changes from one candle to the other.  I'm trying to show coefficient in a separate window with red and white lines.  However metatrader doesn't want to play ball.  Every time I insert the indicator I get either the red lines or the white lines.  I don't get both.  Can someone check my code?

#property indicator_separate_window
#property indicator_buffers 2
#property indicator_color1 Red
#property indicator_color2 White
#property indicator_level1 1.0
#property indicator_level2 -1.0

//--- input parameters
extern   bool   UseCompletedBars = true;
extern string    Symbol1           = "GBPUSD";
extern string  Symbol2        = "EURUSD";
extern int     Periods        = 5;        //number of periods going backwards
extern string  CompFactor     = "iClose"; //iClose, iOpen, iHigh, or iLow
double         Line_0[], Line_1[];
datetime       CurrTime = 0;
datetime       PrevTime = 0;
