# How do I make my monster move?

It says 'steps' is not defined in line 93(indicated in the code). Also, the monster is M which I have made visible on the board. Thanks in advance

```import random

BOARD = [(0, 0), (0, 1), (0, 2),
(1, 0), (1, 1), (1, 2),
(2, 0), (2, 1), (2, 2)]

monster = random.choice(BOARD)
start = random.choice(BOARD)
door = random.choice(BOARD)

#If player, door or monster are random, do it all over again.
if monster == door or monster == start or door == start:
return get_locations()

return monster, door, start

x, y = player

y -= 1

continue
if player == door:

print("You win!")

print("You lose!")
print("Game over")
break

# If it's a bad move, don't change anything

Sorry, it actually says this

You're getting a name error because you haven't assigned a value to the variable "steps", so when you pass it into the move_monster() function, the interpreter doesn't have any idea what to do.

It looks like you copied that from the method definition. Make sure you find the value/variable you really want to pass to that function.

Also, please notice that in your function definition, you never use the steps parameter--you overwrite it with a random choice from the monster's moves list. Maybe you don't need that there at all?

```def move_monster(monster, steps):
x, y = monster
moves = ['LEFT', 'RIGHT', 'UP', 'DOWN']
steps = random.choice(moves)  #  <--- right there you assign a value to 'steps' without ever using the value passed in...
if steps == 'LEFT':

### ... you never really use 'steps' for anything other than storing some information local to the function.
```
