If a person with the flag q but not d attempts the command amx_ban whoever 99999 what happens? At the very least the user should receive a message saying, "You have insufficient access to use this command." in the console. If you're not even getting that then there is something wrong. If that's the case try changing the line:

register_concmd("amx_ban","cmdBan",ADMIN_ADMI N,"<name or #userid> <minutes> [reason]")

to

register_concmd("amx_ban","cmdBan",ADMIN_ALL, "<name or #userid> <minutes> [reason]")

Which will let everyone have access to it but because I have it checking flag by flag, if the user doesn't have either d or q then you will get that message.
