Bill Williams Fractal Indicator for ThinkorSwim

I use the Williams Fractal
https://usethinkscript.com/threads/bill-williams-fractal-indicator-for-thinkorswim.600/
to make entries when the price crosses above the upfractal or below the downfractal. I need a way to create a horizontal line from the plotted indicator upfractal that stays visible until the next upfractal is plotted. Same for the downside. This is the code I'm using to start with:

# Bill Williams fractal indicator
# written by Mike Lapping
#
# Make sure that you change the settings for this indicator so that it plots arrows
# up for upfractal plots
# down for downfractal plots
#
# can be used and modified by anyone for any reason. do not sell.
declare upper;

def isupfractal;
def isdownfractal;

# Looking for high and low series of equalities
# checking for possible fractal formation

rec hicount = If (high == high[1], hicount[1] + 1, 0);
rec hivalid = If (
(hicount[1] == 0 and hicount == 1 and high > high[2] and high > high[3]) or
(hicount[1] and hicount and hivalid[1]) or
(hicount[2] and hivalid[2] and high == high[2] and high > high[1]), 1, 0);

rec locount = If (low == low[1], locount[1] + 1, 0);
rec lovalid = If (
(locount[1] == 0 and locount == 1 and low < low[2] and low < low[3]) or
(locount[1] and locount and lovalid[1]) or
(locount[2] and lovalid[2] and low == low[2] and low < low[1]), 1, 0);

# Checking for a traditional or non-standard up fractal
isupfractal = If(
((hicount and hivalid) or (high > high[1] and high > high[2])) and
high > high[-1] and high > high[-2], high, 0);

# Checking for a traditional or non-standard down fractal
isdownfractal = If(
((locount and lovalid) or (low < low[1] and low < low[2])) and
low < low[-1] and low < low[-2], low, 0);

plot upfractal = If(isupfractal, isupfractal + (1 * TickSize()), Double.NaN);
upfractal.SetPaintingStrategy(PaintingStrategy.TRIANGLES);
upfractal.SetLineWeight(5);

plot downfractal = If(isdownfractal, isdownfractal - (1 * TickSize()), Double.NaN);
downfractal.SetPaintingStrategy(PaintingStrategy.TRIANGLES);

was posted five years ago and the OP is long gone. I'm getting an invalid statement for the section in bold below. I'm sure it's a simple fix.. I tried to figure it out, but I'm not a coder. If someone could fix it, I'll go back to the original post and add it for the next person.

in the addlabel() , the word brilliant looks odd
addlabel(yes, brilliant

i don't think it belongs , but will test something first,

add a comma after it,.. nope , still error.

i add a def at top of code to see if it complains of a duplicate define,
def brilliant = 0;
nope. no error , was not defined , so it doesn't belong. i delete that def.

i delete the word brilliant
it works
