I did what the steps said to do and that doesn't work.
So you are playing on Android? My guess is you did not install version 7.7.1 of the Renpy Plugin. Do the install again with that version, then it works.
More info on the FAQ page in the Wiki and FAQ channel in Discord.
I noticed you asked the same thing 15 days ago, and I answered then same way I answered now. What happened? Did you not use Renpy Plugin version 7.7.1? To find where you can download it, see FAQ page in the Wiki.
But it says it’s missing a line.
What says what is missing a line? The error message you showed (three times) is about syntax error. That error usually happens when Python 2 code is being run on a Python 3 runtime.
I downloaded the most recent version.
Most recent version of what?
If it is Joiplay or Renpy Plugin, like I wrote twice you should not download the latest version but version 7.7.1.
