Error when Creating Flags - Help

[exax]

I am currently writing a Visual Novel and need to establish a fair number of flags.
However, I am having trouble recalling the flags.

In the first script

label note_2:
if note1 == "no_go":
$ hano_flag_1 = True
jump note2_home

In a later script

menu:
"Hano" if hano_flag_1 == True:
$ hano_flag_2 = True
jump note4_afternoon

Error

I'm sorry, but an uncaught exception occurred.

While running game code:
File "game/scripts/note_4.rpy", line 322, in script
menu:
File "game/scripts/note_4.rpy", line 328, in <module>
"Hano" if hano_flag_1 == True:
NameError: name 'hano_flag_1' is not defined

Note
- The same error occurs when I tried to use $ flag = "Yes" or other alternatives names
- The same error occurs when the ($ X = True ) statement and (if X == True) statement in the same script file
- The same error occurs when the ($ X = "Y" ) statement and (if X == "Y") statement in the same script file


Please help me identify the problem >___<

Note: The indentation is not showing in the quotes, but the script is properly indented

Use code tage, not quote tag.

What do you think would happen if somebody will not hit the line setting variable to True? What would be the value of the variable in this case?

You need to make sure that variable always has some value assigned to it. Easiest way do do so is to give it a default value:

Code: Select all

# Outside of any context, even init statements
default hano_flag_1 = False

!!! I forgot about the False value !!!
Thank you so much !
