So I have this here:

switch () {
  case (Yeah...) {
    TextFX_Typewriter ("The brown tabby cat grins and crouches to your level. ''I'm Snakepaw.'' He tells you. ''And i'm one of the strongest apprentices!'' He boasts. A russet and white she-cat came up to Snakepaw. ''Yeah right! Oh, hi " +player.alias + "kit. I'm Cherrypaw. Don't mind my brother- he's a mousebrain.'' Snakepaw stuck out his tongue.", 3)
  }
}

And I can't find out how to make the case name valid. How do I make it so that it won't give me an error for the name of the switch? Is there a way to make a switch manually before it is said??
I'm really new to this type of stuff, so if there is a fix i'd love to know.
Otherwise, are there alternative ways to pick an answer?
Thanks, I really need help, i've been stumped and unable to find an answer for ages.

Okay. After a while I figured it out, it needed to be attached to a menu and a variable like this:

options = Split("Yeah;Can you show me around?", ";")
ShowMenu ("Reply", options, true) {
  ClearScreen
  switch (result) {
    case ("Can you show me around?") {
      TextFX_Typewriter ("The apprentices scoff. ''Sorry, we have to go train. You need to explore yourself.''", 3)
      options = Split("Okay", ";")
      ShowMenu ("Reply", options, false) {
      }
    }
    case ("Yeah") {
      TextFX_Typewriter ("The brown tabby cat grins and crouches to your level. ''I'm Snakepaw.'' He tells you. ''And i'm one of the strongest apprentices!'' He boasts. A russet and white she-cat came up to Snakepaw. ''Yeah right! Oh, hi " +player.alias + "kit. I'm Cherrypaw. Don't mind my brother- he's a mousebrain.'' Snakepaw stuck out his tongue.", 3)
    }
    default {
      msg ("That was not even an option!")
    }
  }
}

(Im putting the answer here in case anybody else would like some help)
