VHDL中出现错误found illegal character 是怎么回事

我在eda编程时，出现66个错误，我不知道怎么回事，哪位高手可以帮我解决吗
程序是这样的，

LIBRARY IEEE;
USE IEEE.STD_LOGIC_1164.ALL;
USE IEEE.STD_LOGIC_UNSIGNED.ALL;
ENTITY kz IS
PORT (CLK1S,car:IN STD_LOGIC;--1S脉冲，支干道车辆检测
TIME1H,TIME1L:OUT STD_LOGIC_VECTOR(3 DOWNTO 0);--主干道计时
TIME2H,TIME2L:OUT STD_LOGIC_VECTOR(3 DOWNTO 0);--支干道计时
count:OUT STD_LOGIC_VECTOR(6 DOWNTO 0); --系统总计时
led:OUT STD_LOGIC_VECTOR(5 DOWNTO 0)); --交通灯显示
END kz;
ARCHITECTURE one OF kz IS
TYPE states IS (s0, s1, s2,s3, s4); --状态初始化

ELSE

current_state <= next_state;
END IF;
END IF;

IF car = '1' THEN next_state <= s1;
ELSE next_state <= s0;
END IF;
