Scrolling Text - 7 Segment Display on DE0-CV

Alright, before I waste my time guessing on what to do, would I assign all the pins to hexout or would I instead somehow fill the array (hexout) with HEX0 to HEX5 (which already have the pins assigned to them)? Here is the code I have come up with so far. I tried to assign the HEX0-HEX5 to the hexout, but error showed up saying I had to change them to a buffer type.

LIBRARY ieee;USE ieee.std_logic_1164.all;
USE work.my_types_pkg.all;
ENTITY hexscroll IS
PORT(
CLOCK_50 : IN STD_LOGIC;
hexout   : OUT hexout_array_t;
HEX0 		: BUFFER STD_LOGIC_VECTOR(6 downto 0);
HEX1 		: BUFFER STD_LOGIC_VECTOR(6 downto 0);
HEX2 		: BUFFER STD_LOGIC_VECTOR(6 downto 0);
HEX3 		: BUFFER STD_LOGIC_VECTOR(6 downto 0);
HEX4 		: BUFFER STD_LOGIC_VECTOR(6 downto 0);
HEX5 		: BUFFER STD_LOGIC_VECTOR(6 downto 0));
END hexscroll;
	
ARCHITECTURE blinkled OF hexscroll IS
	SIGNAL pulse : STD_LOGIC_VECTOR (6 downto 0) := B"010_0100";--variable to hold value of LED
	SIGNAL count : INTEGER RANGE 0 TO 49999999 := 0; --counter variable
	
BEGIN
	counter:PROCESS (CLOCK_50)
	BEGIN
		hexout <= (HEX0, HEX1, HEX2, HEX3, HEX4, HEX5);
		IF CLOCK_50'EVENT AND CLOCK_50 = '1' THEN
			
			IF count = 49999999 THEN
				count <= 0;
				pulse <= NOT pulse;
			ELSE
				count <= count + 1;
			END IF;
		END IF;
	END PROCESS counter;
	--hexout <= ???
END blinkled;

LIBRARY IEEE;USE ieee.std_logic_1164.all;
PACKAGE my_types_pkg IS
  
  TYPE hexout_array_t IS ARRAY(0 to 5) OF STD_LOGIC_VECTOR(6 downto 0);
