password verification, problem with password verify section

code compiles and runs but only goes to the password verification section if the user enters an incorrect password and needs to reenter a correct password. Tried an if/else statement and would not recognize the passwordVerify. Suggestions on how to correct so program continues to verification section after a correct password is entered the first time would be helpful. Thank you
