Hi guys, this might be the last favor I am gonna ask (i know its too much) but can you please point out and fix the problems with this source code. Basically it should automate a login program which has an attempt limiter and if the user and pass is correct it should continue with the program. Thank you very much! Please help me.

Well asa you can see on the 2nd part it is the MENU already. I am only having problems with the login/authentication part and the looping structure.
