My Eyes Are Burning Staring At This Code All Night Help Please!

Hi all! Stupid Oclock in the morning where I am. Well it is to me anyway, I should be in my bed. I’m trying to code a high and low rectangle of certain daily time periods on any timeframe. I can manage one time period but I’m trying to show multiple times and it’s not working out for me. It’s a piece of code I found here and I’m trying to adapt it to show multiple times…here is what I have worked up to…

if intradaybarindex=0 then
maxvalue=0
minvalue=Dclose(0)*5
MyBar=0
endif
timerange = time>=020000 and time<=050000
if timerange  then
maxvalue = max(maxvalue , high)
minvalue = min(minvalue , low)
if MyBar=0 then
x1=barindex
MyBar=1
endif
if time=050000 then
x2=barindex
DRAWRECTANGLE(x1,maxvalue,x2,minvalue) coloured(06,17,79)
endif

maxvalue=0
minvalue=Dclose(0)*5
MyBar=0
endif
timerange = time>=070000 and time<=100000
if timerange  then
maxvalue = max(maxvalue , high)
minvalue = min(minvalue , low)
if MyBar=0 then
x1=barindex
MyBar=1
endif
if time=100000 then
x2=barindex
DRAWRECTANGLE(x1,maxvalue,x2,minvalue) coloured(06,17,79)
endif
endif
RETURN

Would someone be so kind to show me where I’m going wrong?

Thank you!
