Please help with this code.

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])
```
and
```
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.
