  The code below gives me an error of:
  Error 3.Condition in IF, WHILE, FOR 
  statementshas to be Numeric or Boolean type
   
  Problem area highlighted below.
   
  Anyone see the problem?
   
  Thanks

  PS: Does anyone have this code already (John 
  Ehler's Trendline). Trying to convert from Trade Station

  //Detrend Price
  {Value3 = Price - Ref<FONT 
  size=1>(Price,-7);}

  //Use ArcTangent to compute the current phase
  LastInPhase = LastValue<FONT

  if (<FONT color=#0000ff
