here is my code I need help.

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

def pickUpCoin():
    # Collect coins.
    coin = hero.findNearestItem
    if coin:
        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 = friend.findNearestEnemy()
    if enemy:
        hero.command(friend, "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 = friend.findNearestEnemy()
    if enemy > 25:
        hero.command(friend, "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)

Line 8 TypeError: Cannot read property ‘x’ of undefined

What is on line 8?  
hero.moveXY(coin.pos.x, coin.pos.y)

property x of undefined. So coin is undefined.  
you need to define what is coin

coin = hero.findNearestItem?

    if enemy and archer.distanceto(enemy) < 25:
        hero.command(archer, "attack", enemy)
    else:
        hero.command(archer, "move", archer.pos)
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(friends)
            pass

```

You can use archer.findNearestEnemy() there.

You forgot a parenthesis (or is it pair of parenthesis 🤔) at the end of **archer.findEnemies()**

same issue here is my current code

```python
# Ogres are trying to take out your reindeer!

def pickUpCoin():
    # Collect coins.
    if coin:
        coin = hero.findItems()

def commandSoldier(soldier):
    # Soldiers should attack enemies.
    enemy = soldier.findNearestEnemy
    if enemy:

    pass

# Write a commandArcher function to tell your archers what to do!

def commandarcher(archer):

    if enemy and archer.distanceto(enemy) < 25:
        hero.command(archer, "attack", enemy)
    else:
        hero.command(archer, "move", archer.pos)
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.

You need a () at the end of this. Also, try defining soldier as `hero.findNearest(hero.findFriends())` You don’t have it properly defined as a commandable unit, so maybe this will help.

Delete this because you do not need to have anything in between the() from findNearestEnemy.

Also, You are telling your soldiers to attack target, which is an undefined variable. Try using enemy instead in this line:
