Why does the line 32 don’t work ?

```python
# Ogres are trying to take out your reindeer!
# Keep your archers back while summoning soldiers to attack.

def pickUpCoin():
    # Collect coins.
    item = hero.findNearestItem()
    if item:
        hero.move(item.pos)
    pass

def summonTroops():
    # Summon soldiers if you have the gold.
    if hero.gold > 20:
        hero.summon("soldier")
    pass
    
# This function has an argument named soldier.
# Arguments are like variables.
# The value of an argument is determined when the function is called.
def commandSoldier(soldier):
    # Soldiers should attack enemies.
    enemy = soldier.findNearestEnemy()
    if enemy:
        hero.command(soldier, "attack", enemy)
    pass

# Write a commandArcher function to tell your archers what to do!
# It should take one argument that will represent the archer passed to the function when it's called.
# Archers should only attack enemies who are closer than 25 meters, otherwise, stay still.
def commandArcher(archer):
    enemy = archer.findNearestEnemy
    distance = archer.distanceTo(enemy)
    if enemy and distance < 25:
        hero.command(archer, "attack", enemy)
while True:
    pickUpCoin()
    summonTroops()
    friends = hero.findFriends()
    for friend in friends:
        if friend.type == "soldier":
            # This friend will be assigned to the variable soldier in commandSoldier
            commandSoldier(friend)
        elif friend.type == "archer":
            # Be sure to command your archers.
            commandArcher(friend)
            pass

```

Your first and second error lines are:

```python
    enemy = archer.findNearestEnemy
    # your are calling a function and have forgotten something
    distance = archer.distanceTo(enemy)
    # even if the above line is correct you will measure a distance
    # to an object that probably doesn't exist initially 

```

Read what xython has said carefully.  
You’ve seen these things in earlier levels.

My archers just move to the nearest enemy. I read the above messages and I think I have the 2nd problem, but I don’t know how to fix it. Here is my code:

```python
def pickUpCoin():
    # Collect coins.
    coin = hero.findNearestItem()
    hero.moveXY(coin.pos.x, coin.pos.y)
    pass

def summonTroops():
    # Summon soldiers if you have the gold.
    if hero.gold >= hero.costOf("soldier"):
        hero.summon("soldier")
    pass
    
# This function has an argument named soldier.
# Arguments are like variables.
# The value of an argument is determined when the function is called.
def commandSoldier(soldier):
    # Soldiers should attack enemies.
    enemy = soldier.findNearestEnemy()
    if enemy:
        hero.command(soldier, "attack", enemy)
    pass

# Write a commandArcher function to tell your archers what to do!
# It should take one argument that will represent the archer passed to the function when it's called.
# Archers should only attack enemies who are closer than 25 meters, otherwise, stay still.
def commandArcher(archer):
    enemy = archer.findNearestEnemy()
    if enemy and archer.distanceTo(enemy) < 25:
        hero.command(archer, "attack", enemy)
    else:
        pass

while True:
    pickUpCoin()
    summonTroops()
    friends = hero.findFriends()
    for friend in friends:
        if friend.type == "soldier":
            # This friend will be assigned to the variable soldier in commandSoldier
            commandSoldier(friend)
        elif friend.type == "archer":
            # Be sure to command your archers.
            commandArcher(friend)
            pass

```

```python
#you can't write soldier or archer in the functions 
#or it will think that it was a function
#do this:
def commandArcher():
#and
def commandSoldier():
#write ' friends = findFriends()
           #for friend in friends:
           #if friend:
              #if friend.type = ('Archer'#or Soldier)
                   #hero.command(NaN, NaN, NaN) 
#add a distance variable to calculate the distance, use if friend.distanceTo(~~~) in the if stmt.

What is this? Have you written any code yet? Do you need help?  
Please explain your post.

Ok, thanks for trying to help, but please don’t revive old topics. It won’t benefit the original poster (he/she’s not active anymore and has probably solved the problem).
