i need help big time!

here is my screen

and here is my code

```
# You need to find and destroy 3 skeletons.
# Skeletons and items are summoned at points of power.
# Move to a point and say the spell: "VENI".
# To find the required points, use the wizard's map.
# 0s are bad points. Positive numbers are good.
spell = "VENI"
# The map of points is a 2D array of numbers.
wizard = hero.findNearest(hero.findFriends())
powerMap = wizard.powerMap
# This function converts grid into x-y coordinates.
def convert(row, col):
return {'x': 16 + col * 12, 'y': 16 + row * 12}
# Loop through the powerMap to find positive numbers.
# First, loop through indexes of rows.
for i in range(len(powerMap)):
# Each row is an array. Iterate through it.
for j in range(len(powerMap[i])):
# Get the value of the i row and j column.
pointValue = powerMap[i][j]
# If it's a positive number:
if pointValue > 0 and pointValue % 1==0 :
# Use convert to get XY coordinates.
point = convert(i,j)
# Move there, say "VENI" and be prepared!
hero.moveXY(point.pos.x, point.pos.y)
```

What is wrong here?
