The code was developed for a project in which the port maps have a expression...well i couldn't find any brief explanation about this in any of the text books...so if anyone can help me with the error in the code shown below,

Code:
library IEEE;
use IEEE.std_logic_1164.all;
useIEEE.std_logic_unsigned.all;
entity count is
port(clock,csb,ldb:instd_logic;
reset: in std_logic;
drive: out std_logic_vector(8 downto 0);
code: out std_logic_vector(7 downto 0);
scan: in std_logic_vector(4 downto 0);
cd: out std_logic;
rptb: inoutstd_logic;
dab: inoutstd_logic);
end count;
architecturecount_arch of count is
component counter1
port(clk,rst,stop,ldb,csb: in std_logic;
q:inout std_logic_vector(2 downto 0));
end component;
component counter2
port(clk1,rst1,stop1,ldb1,csb1: in std_logic;
qb:inoutstd_logic_vector(4 downto 0));
end component;
component latch1
port(enable,rst2,data: in std_logic;
dout:outstd_logic);
end component;
component decoder35
port(sel: in std_logic_vector(2 downto 0);
decout:outstd_logic_vector(4 downto 0));
end component;

end component;

end component;
