выскакивают ошибки:

(26035) : error 017: undefined symbol "SaveServer"
(26046) : error 017: undefined symbol "SaveServer"
(26274) : error 017: undefined symbol "AntiDeAMX"
(26289) : error 017: undefined symbol "LoadKazino"
(44257) : error 017: undefined symbol "SaveServer"
(44265) : error 017: undefined symbol "SaveServer"

но я хочу обратить внимание на эту ошибку:

(53401) : error 002: only a single statement (or expression) can follow each "case"

как её исправить?

и ещё... я хочу сделать так, чтоб когда игрок встает на пикап, у него начиналась работа (без диалогового окна)
просто подошел на пикап, тебе написало в чате - пора работать и появился первый чикпоинт.
