i make my own version of it, can't really stand ur indentation lol, if u still insist on ur version just take the related chunk and implement it urself
i don't quite understand what u want but the way i done is
>enter id
>check id from names.txt
>if exist ask to select where to go (bathroom, office, nurse, others)
>open next page showing the name of the ID, going to where and when
