warning 219: local variable "zone" shadows a variable at a preceding level //means you've got the same variable defined twice or more times that conflict with eachother
error 017: undefined symbol "GetPlayer2DZone" //means the function is not defined/doesn't exist
warning 203: symbol is never used: "ret_memcpy" //never had this problem but if you used search it would give you an answer to use #pragma unused ret_memcpy
warning 203: symbol is never used: "zarea" //variable has been created but doesn't get used in the script making it pointless
