need help,,newbie for VHDL...

[friendz101]

I am trying to do my assignment, I got this error in my port map

Error (10500): VHDL syntax error at FA.vhd(34) near text "port";  expecting "(", or "'", or "."
Error (10500): VHDL syntax error at FA.vhd(38) near text ")";  expecting "<="

this my program...the error is in my port map???
I am newbie in Quartus...help me plz...

port map error...someone help me plz!!

you should add both instantiation name and module name

instead of
RegA port map( dataA,ldA,clk,rst,Ain);

write

inst_RegA : RegA port map( dataA,ldA,clk,rst,Ain);

Re: port map error...someone help me plz!!

thanks for the reply..and it's work


but I got another problem.

I am got this error for my program,

Error (10454): VHDL syntax error at FA.vhd(217): right bound of range must be a constant

entity RegM1 is
port (	ldsh,w,clk,en,rst	: 	in std_logic;
		d			:	in std_logic_vector(21 downto 0);
		q			:	buffer std_logic_vector(21 downto 0));
end RegM1;


architecture archRegM1 of RegM1 is 
signal X : integer range 0 to 255; 

begin
	process(clk,rst)begin
		if rst = '1' then q	<=(others =>'0');
		elsif(clk'event and clk = '1')then
				if en = '1' then 
						if ldsh = '1' then q <= d;
						else
						q(21) <=w;
											
						X <= CONV_INTEGER(d);
						for i in 0 to X  loop
							q(i)<=q(i+1);
						end loop;
						end if ;
				end if;
		end if;					
end process;
end archRegM1;

how I fix this??
I want to shift this register depend on the result of the other process??
how I should do... help me!!!
