Need help with simple coding

Hi, i recently got this as an assigment but i cant compile to make it work. Hope you guys can help me out. THANKS !

The question
Write a description of a counter that can count up on the negative clock edge. When counting up, the counter counts in binary from 2 to 7 and repeats. When resetting the counter with a LOW signal at the reset input, the counter’s output value is 2. An Led is lit when the output reaches a value of 7

What i done so far

library ieee;
use ieee.std_logic_1164.all;
use iee.numeric_std.all;

entity counter_up is

port (clk, reset_bar : in std_logic;
led_out : out std_logic;
q : out std_logic_vector ( 3 downto 0);

end counter_up;

architecture flow of counter_up is

signal count_up : unsigned ( 3 downto 0);

begin
process ( clk, reset_bar)
begin
if ( reset_bar ='0') then
count_sig <="0010";

elsif falling_edge (clk) then
if (count_sig =7 ) then
count_sig <= "0010";
(led_out = '1')
count_sig <="0111";


else
count_sig<= count_sign +1;


end if;
end if;

end process;

q<= std_logic_vector (count_sig);

end flow;

My lect told me something wrong with this but he does not want to tell where when wrong. I will be grateful if you guys fix this for me. Thanks
