Invalid syntax error in a point based ending system

[AmazingA]

I've been working on a VN and it has a point based ending system. I have seen and cross checked it, but I am getting an invalid syntax error. Here is the error file:
I'm sorry, but errors were detected in your script. Please correct the
errors listed below, and try again.

Here is some of the code where the errors are:

Code: Select all

init:
    python:
        def max_points(*values):
            return [ i for i, v in enumerate(values) if v == max(values) ]

    $ practice points = 0
    $ happiness points = 0
    $ spirit satisfaction = 0
    
menu:

         "Wake up.":
               $ happiness points += 1
               jump choice1_yes  

          "Nah, just a little bit more sleep.":
               jump choice1_no
menu:       
             
          "Invite him to sit and have breakfast.":
              $ happiness points += 1 
              jump choice2_yes  
     
          "Nah, he must've had food already.":
                jump choice2_no

(This is just some of the error code.)
Please help me fix these.
Thanks

Variables can't have spaces in them. Use happiness_points, practice_points, etc.

I'm guessing you're new to programming - just to clarify something:

You'll see that in the Renpy language you can define images with spaces in them, and it may make you think that you can do that with variables. But images aren't actually variables at all, they're renpy specific objects utilising a hierarchical tagging system - and you define them all starting the line with the renpy specific keyword "image".

So the thing to remember is - variables can't have spaces (nor most symbols like -,.$%£@!* etc. Underscore is safe though as Rayne pointed out). Images can have spaces.

Thanks! I am new to programming (as you already guessed ) and this helped me a lot. I was stuck because of this bug. Thanks!
