FSM behaving strangely

I have a simple set of VHDL code that steps through an FSM doing certain things. It compiles fine and I can design my test waveform. However when I run the simulation some of the pins don't show up in the results and outputs that are goverened by what happens to those pins don't get any values.

LIBRARY ieee;
USE ieee.std_logic_1164.all;
USE ieee.numeric_std.all ;
USE ieee.std_logic_unsigned.all;
ENTITY fsm IS
    PORT(clock,reset,isLoadInstruction,isStoreInstruction,isAddInstruction,isMultiplyInstruction,regSource1,regSource2,regDestination: IN STD_LOGIC;
		 PC: BUFFER STD_LOGIC_VECTOR(15 DOWNTO 0);
         readInstructionMemory,readRegs,writeRegs,performAdd,performMultiply,readDataMemory,writeDataMemory: OUT STD_LOGIC);
END fsm;
ARCHITECTURE Behavior OF fsm IS
