It's better if you post and host your code in workspaces that way we can easily see and modify if need be.

  1. Go to: https://teamtreehouse.com/workspaces
  2. Click on "New +"
  3. Name workspace
  4. Select environment "Python"
  5. Create

Since workspaces preview only lives temporarily create a snapshot.

  1. Click snapshot (First icon on top right corner)
  2. Share snapshot link https://w.trhou.se/rpuj2yjpwg

Can you please post the stack trace from the error message?

This will show what the code was doing during the error.

:point_right: Your code is a bit different from the code in the video.

As shown in the video "Dry", the attack routine first places a random number in a variable named "roll". But the same method in your version of combat.py places the random number in a variable named "attack". So when the next statement tries to reference the variable using the name "roll", it does not exist (and is therefore "not defined").
