Why am I getting an "Undeclared identifier" error when it appears that I did identify it?

Question

Inside_Bar = high[1] > high[0] and low[1] < low[0]
Prev_Range = high[1] - low[1]
Bullish = open[1] < close[1]
Bearish = open[1] > close[1]

// Get Key Levels 
Long_Stop_Buy_Level = high[1] + Prev_Range * Stop_Buy_Perc
Short_Stop_Buy_Level = low[1] - Prev_Range * Stop_Buy_Perc
Long_Stop_Loss_Level = high[1] - Prev_Range * Stop_Loss_Perc
Short_Stop_Loss_Level = low[1] + Prev_Range * Stop_Loss_Perc
Long_Take_Prof_Level = high[1] + Prev_Range * Take_Prof_Perc
Short_Take_Prof_Level = low[1] - Prev_Range * Take_Prof_Perc

// Position Sizing
long_qty = math.floor(strategy.equity * Risk)
short_qty = math.floor(strategy.equity * Risk)

// -------------------------- LONG CONDITIONS --------------------------------//
Long_Condition = Window and Inside_Bar and Bullish
if Long_Condition
    // Incase we still have a buy stop order in the market
    strategy.cancel_all()
    // Close any existing positions according to the rules
    strategy.close_all()
    strategy.entry('Bullish IB', strategy.long, stop=Long_Stop_Buy_Level, qty=long_qty)

The error

Error at 58:36 Undeclared identifier 'Short_Condition'

I copied the alert script from the V5 manual and modified it a bit to suit my strategy. I'm trying to get the alerts to go off at the strategy's entry and exit points but I'm running into (Undeclared identifier 'Short_Condition').

What's really strange is that the "Short_Condition" error I get with the pasted in alert script is not showing up when I run the same strategy script without the alert script. Any advice is greatly appreciated.

Your Short_Condition was in use before you defined it used at line 38, defined at line 52.

All variables should be defined before using
