New to VHDL. Help with errors

Hi,

Changed as below:

PROCESS(clock,input)

BEGIN

IF RISING_EDGE(clock) THEN

IF (hardwarecontrol = '1') THEN

cs <= '0';

ldac <= '1';

IF (count = "0000") THEN

sdi <= '0';

ELSIF (count = "0001") THEN

sdi <= '1';

ELSIF (count = "0010") THEN

sdi <= '0';

ELSIF (count = "0011") THEN

sdi <= '1';

ELSIF (count = "0100") THEN

sdi <= input(11);

ELSIF (count = "0101") THEN

sdi <= input(10);

ELSIF (count = "0110") THEN

sdi <= input(9);

ELSIF (count = "0111") THEN

sdi <= input(8);

ELSIF (count = "1000") THEN

sdi <= input(7);

ELSIF (count = "1001") THEN

sdi <= input(6);

ELSIF (count = "1010") THEN

sdi <= input(5);

ELSIF (count = "1011") THEN

sdi <= input(4);

ELSIF (count = "1100") THEN

sdi <= input(3);

ELSIF (count = "1101") THEN

sdi <= input(2);

ELSIF (count = "1110") THEN

sdi <= input(1);

ELSIF (count = "1111") THEN

sdi <= input(0);

cs <= '1';

ldac <= '0';

shdn <= '1';

END IF;

count <= count +1;

ELSIF (hardwarecontrol = '0') THEN

count <= "0000";

END IF;

END IF;

END PROCESS;
