Great response lemelleio, you should post it as an answer instead of a comment.
If I was a moderator, I'd have promoted it for you.

Hey Aly

Your code is almost right:

number = 3 
#setting the initial value is not necessary, 
#the code challenge will pass its own value into your function,
#in order to test your code.

def square(total):  
    total = number ** 2
    return total
# the issue with your function is the test passes in 5(for example) as total, 
#you then reassign total(5) to a new the value of the variable "number", to the power of 2. 
#well the variable "number" has no value, as you did not assign it any. 
#so its value is NULL, you then return the reassigned total (which is now NULL).


result = total
#no need to assign a new variable here, 
#the test only wants you to return a squared number of the parameter passed into the function.


#example solution
def square(number):
    return number ** 2
