Can't seem to figure out what's wrong.

Neither can we without seeing all the code . . . how have you declared the buffer Buf_0 ?

[mankin2006]

#property indicator_separate_window
#property indicator_buffers 1
#property indicator_color1 Blue

extern int History =50;  
extern int Aver_Bars =5;

double Buf_0;
//+------------------------------------------------------------------+
//| Initialization function                              |
//+------------------------------------------------------------------+

int init()
  {
   SetIndexBuffer(0,Buf_0);
   SetIndexStyle(0,DRAW_LINE,STYLE_SOLID,2);
   return;
  }
//+------------------------------------------------------------------+

Here this might clarify some things, thanks for the response

OK, this isn't a buffer, it's just a double variable . . .

double Buf_0;

. . . read here and look at the sample code: IndicatorBuffers()
