Ok, so I’m trying to get the script to have a character type they’re name but every time I click save preview and run the script, the username is just autobot and I can’t actually type one.
Here’s my script:
label first_name_input
input What’s Your First Name?|What’s Your First Name?|Done(FIRSTNAME)
if (FIRSTNAME is “”) {
NARRATOR
You do need a name...
goto first_name_input
} else {
continue
}
Your script is fine. Unfortunately, you can’t type in or see names on the web previewer yet, only when you preview it on your device. It should work then! 
I can feel you, I felt confused the first time too.
@goth.gaia is right, script is fine! The web previewer shows autobot, but testing your story on a device shows the name if you type it in.
Also, you don’t need to include that extra stuff to allow a reader to type in a name, all you need to write is:
input What’s Your First Name?|What’s Your First Name?|Done(FIRSTNAME)
Much less work, right?
