implicit conversion from 'number' to 'string' error on my custom fibo indicator

New comment
 

i am getting this error  " implicit conversion from 'number' to 'string' 

i am still new to coding and i am trying to figure out why this would cause this error.     

Section below is where the error is being generated

   SetIndexLabel(0,"Fibo("+BandsPeriod+")["+TimeFrame+"]");
   SetIndexLabel(1,"Fibo("+BandsPeriod+")Up1 "+BandsFiboDeviation1+"["+TimeFrame+"]");
   SetIndexLabel(2,"Fibo("+BandsPeriod+")Lo1 "+BandsFiboDeviation1+"["+TimeFrame+"]");
   SetIndexLabel(3,"Fibo("+BandsPeriod+")Up2 "+BandsFiboDeviation2+"["+TimeFrame+"]");
   SetIndexLabel(4,"Fibo("+BandsPeriod+")Lo2 "+BandsFiboDeviation2+"["+TimeFrame+"]");
   SetIndexLabel(5,"Fibo("+BandsPeriod+")Up3 "+BandsFiboDeviation3+"["+TimeFrame+"]");
   SetIndexLabel(6,"Fibo("+BandsPeriod+")Lo3 "+BandsFiboDeviation3+"["+TimeFrame+"]");


Below is the entire custom indicator.

//+------------------------------------------------------------------+

int init()
  {
   SetIndexBuffer(0,MovingBuffer);
   SetIndexBuffer(1,UpperBuffer1);
   SetIndexBuffer(2,LowerBuffer1);
   SetIndexBuffer(3,UpperBuffer2);
   SetIndexBuffer(4,LowerBuffer2);
   SetIndexBuffer(5,UpperBuffer3);
   SetIndexBuffer(6,LowerBuffer3);
 
 
         if(TimeFrame==0) TimeFrame = Period();
//
   SetIndexShift(0,BandsShift*TimeFrame/Period());
   SetIndexShift(1,BandsShift*TimeFrame/Period());
   SetIndexShift(2,BandsShift*TimeFrame/Period());
   SetIndexShift(3,BandsShift*TimeFrame/Period());
   SetIndexShift(4,BandsShift*TimeFrame/Period());
   SetIndexShift(5,BandsShift*TimeFrame/Period());
   SetIndexShift(6,BandsShift*TimeFrame/Period());

   SetIndexLabel(0,"Fibo("+BandsPeriod+")["+TimeFrame+"]");
   SetIndexLabel(1,"Fibo("+BandsPeriod+")Up1 "+BandsFiboDeviation1+"["+TimeFrame+"]");
   SetIndexLabel(2,"Fibo("+BandsPeriod+")Lo1 "+BandsFiboDeviation1+"["+TimeFrame+"]");
   SetIndexLabel(3,"Fibo("+BandsPeriod+")Up2 "+BandsFiboDeviation2+"["+TimeFrame+"]");
   SetIndexLabel(4,"Fibo("+BandsPeriod+")Lo2 "+BandsFiboDeviation2+"["+TimeFrame+"]");
   SetIndexLabel(5,"Fibo("+BandsPeriod+")Up3 "+BandsFiboDeviation3+"["+TimeFrame+"]");
   SetIndexLabel(6,"Fibo("+BandsPeriod+")Lo3 "+BandsFiboDeviation3+"["+TimeFrame+"]");

       if (TimeFrame < Period()) TimeFrame = Period();

 
   return(0);
  }

any advice would be great thanks.

 
  1. Ricks creations: i am getting this error  " implicit conversion from 'number' to 'string'  

    SetIndexLabel(0,"Fibo("+BandsPeriod+")["+TimeFrame+"]");

    Appending a number to a string.

    Stop implicitly converting. Use a cast, IntegerToString, or StringFormat.

    SetIndexLabel(0, StringFormat("Fibo(%d)[%s]", BandsPeriod, TimeFrame) );
  3. No idea what TimeFrame is since you didn't provide post all relevant code (using Code button) or attach the source file.
