  Please help with this code. It is coming up with errors

   

  // Parameters
  lookbackPeriod = 10

  // Number of bars to look back for pivot highs and lows

  // Variables to store pivot points
  pivotHighPrice = 0
  pivotLowPrice = 0

  // Find Pivot High (downtrend)
  for i = 1 to LookbackPeriod do
  if high[i] > high[i+1] and high[i] > high[i-1] then
  pivotHighPrice = high[i]
  break
  endif
  next

  // Find Pivot Low (uptrend)
  for i = 1 to LookbackPeriod do
  if low[i] < low[i+1] and low[i] < low[i-1] then
  pivotLowPrice = low[i]
  break
  endif
  next

  // DeMark Trendline Logic
  // For Uptrend: connecting pivot low to subsequent lower low
  if pivotLowPrice= 0 then
  lineUp =DRAWLINE(pivotLowPrice, Date[pivotLowBar], low, Date[0])
  endif

  // For Downtrend: connecting pivot high to subsequent higher high
  if pivotHighPrice = 0 then
  lineDown = DRAWLINE(pivotHighPrice, Date[pivotHighBar], high, Date[0])
  endif

  RETURN lineUp AS “DeMark Up Trendline”, lineDown AS “DeMark Down Trendline”

  DrawLine is a graphical instruction, not to be used in expressions.

  Use:

  DRAWLINE(pivotLowPrice, Date[pivotLowBar], low, Date[0])

  1	DRAWLINE(pivotLowPrice, Date[pivotLowBar], low, Date[0])

  and

  DRAWLINE(pivotHighPrice, Date[pivotHighBar], high, Date[0])

  1	DRAWLINE(pivotHighPrice, Date[pivotHighBar], high, Date[0])

  Bear in mind that DrawLine (https://www.prorealcode.com/documentation/drawline/) requires BARINDEX1,PRICE1,BARINDEX2,PRICE2 to draw a line between two points.
