How do i reset variable 1 if the conditions for variable 2 arent met?

I tried to reset it  8 bars after variable 1, seems to not work.

When the high is < bolldown this is variable 1. I named it trigger = 1.

When trigger = 1 is active and within 8 bars if price closed above bollup i named it trigger =2 ( variable 2).

If it dosent close above bollup within 8 bars i tried to reset it back to trigger =0.

Im sorry i know my explanation is a little confusing.

Defparam cumulateorders = false
DEFPARAM FLATBEFORE = 090000
DEFPARAM FLATAFTER = 160000
daysForbiddenEntry = OpenDayOfWeek = 6 OR OpenDayOfWeek = 0

//INDICATORS
c1 = AverageTrueRange[14](close) > 2
c2 = ExponentialAverage[200](close)
Bollup = CALL "Example2 : Bollinger(1)upup"[0.66, 10]
Bolldown = CALL "Example2 : Bollinger(1)down"[0.66, 10]

//SIGNALS 
once trigger = 0 
ONCE trigger = 1
if trigger = 0 and  high < bolldown  then
trigger = 1
triggersignal = barindex
endif
if (barindex-triggersignal) >8 then
trigger = 0
endif
if trigger = 1 and close > bollup then
trigger = 2
endif

//BUY CONDITIONS
IF Trigger = 2  and c1 and close>c2 and bolldown > c2 AND Not OnMarket and not daysForbiddenEntry THEN
BUY 1 Contract AT market 
SET TARGET pPROFIT 10
SET STOP   ploss 10
Trigger = 0
ENDIF

This is the full code.
