In your original post
Using what you know about search arrays, implement the VerifyUsername and VerifyPassword functions. They should return true if the username or password is found in the arrUsernames or arrPasswords array, respectively.
Your code doesn't do that, all your functions do is Return True.

Code:
 Function VerifyUsername(username As String) As Boolean
        'If the username is found, Return True, otherwise Return False
        Return True
    End Function

    Function VerifyPassword(password As String) As Boolean
        'If the passwords match, Return True, otherwise Return False
        Return True
    End Function
You put the code for verifying the UserName and Password in the LogIn procedure.

Thank you for your recent project submission. Unfortunately, I cannot grade your work at this time because you did not code the VerifyUsername and VerifyPassword Functions properly in your program.
It seem your instructor wants you to move your verification code to those functions.
