model i need to build. Yet, it doesn't work :(

the purpose of the code is very simple. I have a step motor i connect to a circuit matrix. the circuit matrix has a ULN2803 transistor. And the matrix is connected to an Altera EPF10K70 device . i need to make the motor turn right at my command (pressing a button on the altera) and turn left at the pressing of the other button. every button pressing is to adjust the motor to the side by a click. Meaning, that one short press only moves it slightly, and a long press keeps it moving until i stop pressing it.

but it doesn't work :(

I have to assign this project for next sunday, or else i'll flank this course.. pls people - i desperetaly need ur help!

here's the code i did:


entity MOTOR2 is
port
(out1_rl, out2_rl, out3_rl, out4_rl : out std_logic;
right, left : in std_logic);
end MOTOR2;

architecture behave of MOTOR2 is
Begin
process (right)
VARIABLE temp_rl : INTEGER RANGE 1 TO 4;
Begin
temp_rl:=1;
if (temp_rl=1) then
out2_rl<='1';
temp_rl:=2;
end if;
if (temp_rl=2) then
out3_rl<='1';
temp_rl:=3;
end if;
if (temp_rl=3) then
out4_rl<='1';
temp_rl:=4;
end if;
if (temp_rl=4) then
out1_rl<='1';
temp_rl:=1;
end if;
end process;
end behave;
