Quartus Error: Object is used but not declared

[Xevon]

I am getting : Error (10482): VHDL error at sevensegproj.vhd(144) : object 'e' is used but not declared.

As far as I can tell it is declared.. just started using vhdl this semester for my class. I am making a seven segment display and am in the middle of debugging so excuse my lack of knowledge. Here is a portion of the code where I think the error may be (the code is like 500 lines long probably shouldn't post it all so only doing a portion) :

entity Proj is
port
(
A: in std_logic_vector (2 downto 0);
A1: in std_logic;
A2: in std_logic_vector (3 downto 0);
A3: in std_logic;
A4: in std_logic;
LS, RS: out std_logic_vector (6 downto 0)
);
END Proj;

Architecture struct of Proj is
--skipping a lot of code right here--

component rselect is
port(
b: in std_logic;
e: in std_LOGIC;
fr: in std_logic_vector (3 downto 0);
rz, ro: out std_logic_vector (3 downto 0);
A: in std_logic_vector (2 downto 0));
end component;

component resultsel is
port(
b: in std_logic;
e: in std_logic_vector (3 downto 0);
qz, qo: in std_logic_vector (3 downto 0);
re: out std_logic_vector (3 downto 0));
end component;
component segprocess is
port(
re: in std_logic_vector (3 downto 0);
otL,otR : out std_logic_vector (3 downto 0));
end component;
component Reg is
port(
upd, reset: in std_logic;
f: in std_logic_vector (3 downto 0);
g: out std_logic_vector (3 downto 0)
);
end component;
component sevensegproj is
port(
bcd: in std_logic_vector (3 downto 0);
seg7: out std_logic_vector (6 downto 0)
);
end component;

signal re,Qz,Qo,otL,otR: std_logic_vector (3 downto 0);
signal r0,r1,r2,r3,r4,r5,r6,r7,rz,ro,fr: std_logic_vector (3 downto 0);
signal reset1: std_logic;

--this is where the error is--
RegSelector: rselect port map(A4, e, fr, rz, ro, A);
ResultSelector: resultsel port map(A4, e, qz, qo, re);


entity rselect is
port (
b: IN STD_LOGIC;
e: IN STD_LOGIC;
fr: IN STD_LOGIC_VECTOR (3 downto 0);
rz, ro: out STD_LOGIC_VECTOR (3 downto 0);
A: in STD_LOGIC_VECTOR (2 downto 0));
end rselect;

architecture func of rselect is
BEGIN
process (A,e,fr) begin
if A /= "100" then
if e ='0' then
rz <= fres;
ro <= "0000";
elsif e = '1' then
ro <= fres;
rz <= "0000";
end if;
elsif A = "100" then
if e = '1' then
rz <= fr;
ro <= "0000";
elsif e='0' then
ro <= fres;
rz <= "0000";
end if;
end if;
end process;
end func;


library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
use IEEE.STD_LOGIC_ARITH.ALL;
use IEEE.STD_LOGIC_UNSIGNED.ALL;

entity resultsel is
port (
b: IN STD_LOGIC;
e: IN STD_LOGIC;
qz, qo: IN STD_LOGIC_VECTOR (3 downto 0);
re: out STD_LOGIC_VECTOR (3 downto 0));
end resultsel;

architecture func of resultsel is

end if;
end process;
end func;


This is due tomorrow. It all makes somewhat sense to me just don't know why e isn't working when everything else is

You didn't post the file sevensegproj.vhd which is where your problem is located.

quartus is correct- you have not declared e inside the "Proj" entity.
