How can I fix the 'end of line without line continuation' error in TradingView's Pine Editor?

Question

I have no idea why I keep getting this error on the line with the longFillColor… I tried adding the colon & I tried splitting the code across multiple lines, but to no avail. It says that it is a syntax error, but I'm unable to locate the inconsistency.

//@version=5
indicator("Supertrend", overlay=true, format=format.price, precision=2)

Periods = input.int(title="ATR Period", defval=10, minval=1)
src = input(close, title="Source")
Multiplier = input.float(title="ATR Multiplier", defval=3.0, minval=0.1, step=0.1)
changeATR = input.bool(title="Change ATR Calculation Method?", defval=true)
showsignals = input.bool(title="Show Buy/Sell Signals?", defval=true)
highlighting = input.bool(title="Highlighter On/Off?", defval=true)

atr2 = ta.sma(ta.tr, Periods)
atr = changeATR ? ta.atr(Periods) : atr2

up = src - (Multiplier * atr)
up1 = ta.valuewhen(ta.close[1] > up[1], up, 1)
up := ta.close[1] > up1 ? math.max(up, up1) : up

dn = src + (Multiplier * atr)
dn1 = ta.valuewhen(ta.close[1] < dn[1], dn, 1)
dn := ta.close[1] < dn1 ? math.min(dn, dn1) : dn

trend = 1
trend := ta.valuewhen(trend[1] == -1 and ta.close > dn1, 1, 1)
trend := ta.valuewhen(trend[1] == 1 and ta.close < up1, -1, 1)

upPlot = plot(trend == 1 ? up : na, title="Up Trend", color=color.new(color.green, 0), linewidth=2)
buySignal = trend == 1 and trend[1] == -1
plotshape(buySignal ? up : na, title="UpTrend Begins", location=location.absolute, style=shape.circle, size=size.tiny, color=color.new(color.green, 0))

dnPlot = plot(trend == 1 ? na : dn, title="Down Trend", color=color.new(color.red, 0), linewidth=2)
sellSignal = trend == -1 and trend[1] == 1
plotshape(sellSignal ? dn : na, title="DownTrend Begins", location=location.absolute, style=shape.circle, size=size.tiny, color=color.new(color.red, 0))

mPlot = plot(ta.ohlc4, title="", style=plot.style_circles, linewidth=0)
longFillColor = highlighting ? (trend == 1 ? color.new(color.green, 80) : color.new(color.white, 0))
shortFillColor = highlighting ? (trend == -1 ? color.new(color.red, 80) : color.new(color.white, 0))
fill(mPlot, upPlot, title="UpTrend Highlighter", color=longFillColor) :
fill(mPlot, dnPlot, title="DownTrend Highlighter", color=shortFillColor) :

alertcondition(buySignal, title="SuperTrend Buy", message="SuperTrend Buy!")
alertcondition(sellSignal, title="SuperTrend Sell", message="SuperTrend Sell!")

changeCond = trend != ta.valuewhen(trend[1] != trend[1], trend, 1)
alertcondition(changeCond, title="SuperTrend Direction Change", message="SuperTrend has changed direction!")

You've got some other errors in there as well. There is no ta.close or ta.ohlc4 its just simply close or ohlc4 regardless this should work now. You needed to add another : and condition to your longfillcolor and shortfillcolor arguments

//@version=5
indicator("Supertrend", overlay=true, format=format.price, precision=2)

Periods = input.int(title="ATR Period", defval=10, minval=1)
src = input(close, title="Source")
Multiplier = input.float(title="ATR Multiplier", defval=3.0, minval=0.1, step=0.1)
changeATR = input.bool(title="Change ATR Calculation Method?", defval=true)
showsignals = input.bool(title="Show Buy/Sell Signals?", defval=true)
highlighting = input.bool(title="Highlighter On/Off?", defval=true)

atr2 = ta.sma(ta.tr, Periods)
atr = changeATR ? ta.atr(Periods) : atr2

up = src - (Multiplier * atr)
up1 = ta.valuewhen(close[1] > up[1], up, 1)
up := close[1] > up1 ? math.max(up, up1) : up

dn = src + (Multiplier * atr)
dn1 = ta.valuewhen(close[1] < dn[1], dn, 1)
dn := close[1] < dn1 ? math.min(dn, dn1) : dn

trend = 1
trend := ta.valuewhen(trend[1] == -1 and close > dn1, 1, 1)
trend := ta.valuewhen(trend[1] == 1 and close < up1, -1, 1)

upPlot = plot(trend == 1 ? up : na, title="Up Trend", color=color.new(color.green, 0), linewidth=2)
buySignal = trend == 1 and trend[1] == -1
plotshape(buySignal ? up : na, title="UpTrend Begins", location=location.absolute, style=shape.circle, size=size.tiny, color=color.new(color.green, 0))

dnPlot = plot(trend == 1 ? na : dn, title="Down Trend", color=color.new(color.red, 0), linewidth=2)
sellSignal = trend == -1 and trend[1] == 1
plotshape(sellSignal ? dn : na, title="DownTrend Begins", location=location.absolute, style=shape.circle, size=size.tiny, color=color.new(color.red, 0))

mPlot = plot(ohlc4, title="", style=plot.style_circles, linewidth=0)
longFillColor = highlighting ? trend == 1 ? color.new(color.green, 80) : color.new(color.white, 0) : na
shortFillColor = highlighting ? trend == -1 ? color.new(color.red, 80) : color.new(color.white, 0) : na
fill(mPlot, upPlot, title="UpTrend Highlighter", color=longFillColor)
fill(mPlot, dnPlot, title="DownTrend Highlighter", color=shortFillColor)

alertcondition(buySignal, title="SuperTrend Buy", message="SuperTrend Buy!")
alertcondition(sellSignal, title="SuperTrend Sell", message="SuperTrend Sell!")

changeCond = trend != ta.valuewhen(trend[1] != trend[1], trend, 1)
alertcondition(changeCond, title="SuperTrend Direction Change", message="SuperTrend has changed direction!")
