Having trouble getting a yes/no prompt to appear

[pandajenni]

I've been working on developing a project for a research study, the final project is mostly done, I'm just trying to add tweaks to it. My problems begin with trying to use a Y/N prompt, getting one to appear that is. The line of code I use looks like this: $layout.yesno_screen ("Choose this music?", yes=renpy.jump("choice_hap"), no=renpy.jump("returnPoint"))


I'm failing in getting the yes no screen to appear, along with the y/n screen I'm trying to develop a return point which coding looks like this:

Code: Select all

label MusicSelect:
    $ musicList = ["SoramimiCake.mp3", "Epic.mp3", "Troika.mp3" ]
    $ index = -1 
label returnPoint:
python: 
    index +=1
    if index > len(musicList):
        index = 0
"Please choose the music you would like to hear."
menu: 
    
    "GOAL: How would you keep your focus while driving?"
    with dissolve
    "[musicList[index]]"
    "[hap1]":
        $layout.yesno_screen ("Choose this music?", yes=renpy.jump("choice_hap"), no=renpy.jump("returnPoint"))

When I input that code I keep getting an error message that states: list indices must be integers not unicode

Is there anyone who knows where I went wrong in the code?

Wrap your code in

Code: Select all

 tags so we can see the indentations please.

As Iyale stated, please wrap your code in a code block

I believe your problem is your

Code: Select all

"musicList[index]"

try saving that value in it's own variable first and then use it in the text:

Code: Select all

$ musicAtIndex = musicList[index]

Code: Select all

"[musicAtIndex]"
