Tell us what’s happening:

I don’t see the problem can anyone else see it?

Your encrypt function should return caesar(text, shift).

Your code so far

def caesar(text, shift, encrypt=True):

    if not isinstance(shift, int):
        return 'Shift must be an integer value.'

    if shift < 1 or shift > 25:
        return 'Shift must be an integer between 1 and 25.'

    alphabet = 'abcdefghijklmnopqrstuvwxyz'

    if not encrypt:
        shift = - shift
    
    shifted_alphabet = alphabet[shift:] + alphabet[:shift]
    translation_table = str.maketrans(alphabet + alphabet.upper(), shifted_alphabet + shifted_alphabet.upper())
    encrypted_text = text.translate(translation_table)
    return encrypted_text


# User Editable Region

def encrypt(text, shift):
    return caeser(text, shift)
def decrypt(text, shift):
    return caeser(text, shift, False)

# User Editable Region


encrypted_text = caesar('freeCodeCamp', 3)
print(encrypted_text)
