I am struggling on the "Password Verification" problem

solemnservant (12)
I have been working on this problem for a while and I cannot get the program to accept my arguments. The problem requires a password to be at least six characters long, have at least 1 lower and uppercase letter, and 1 digit. The program should verify if password is acceptable or not. I do not have any error messages, but the program does not work when the listed criteria is entered. Here is what I coded:

Can anyone help me out?

Ok, I have it solved. I got some help on another board. Changed the !isupper and the likes to issupper and tested true instead of false. This fixed my problem. If anyone needs me to post my results just reply here. Thanks.

May I note that your "Congratulatory message if passoword is valid" will only show if the password is entered correctly on the very first go... Just remove the if and put the statement on it's own underneith the while loop before the program exits.

Also you don't need to call all the functions in pswordVerify(...), just remove them and leave but leave the function calls in the variable assignment.
