HDL node not picking up push button signals

Question

Hello,
I am trying to design a vending machine using sbRIO and Labview HDL node. But my HDL node doesn't seem to pick signals from push button (latched when released). I have successfully done the same thing using labview blocks but not geting desired results by HDL node. I could use labview blocks only and not HDL node but I have to give a presentation to my class about how we can integrate VHDL code in labview. I have attached my VI with following VHDL code living inside HDL node. 
process( clk, reset )
begin
if( reset = '1' ) then
state_reg <= idle;
enable_out <= '0';
elsif rising_edge(clk) then
state_reg <= state_next; -- result and enable_out follow input by 1 clock cycle
if( enable_clr = '1' ) then
enable_out <= '0';
elsif( enable_in = '1' ) then
enable_out <= '1';
end if;
end if;
end process;
process(state_reg,Five,Ten)
begin
case state_reg is
when idle=>
if (Five="0"and Ten="0") then
state_next<=idle;
elsif (Five="1" and Ten="0") then
state_next<=statefive;
elsif (Five="0" and Ten="1") then
state_next<=stateten;
elsif (Five="1" and Ten="1") then
state_next<=statedone;
end if;
when statefive=>
if (Five="0" and Ten="0") then
state_next<=statefive;
elsif (Five="0" and Ten="1") then
state_next<=statedone;
elsif (Five="1" and Ten="0") then
state_next<=stateten;
elsif (Five="1" and Ten="1") then
state_next<=statedone;
end if;
when stateten=>
if (Five="0" and Ten="0") then
state_next<=stateten;
elsif (Five="0" and Ten="1") then
state_next<=statedone;
elsif (Five="1" and Ten="0") then
state_next<=statedone;
elsif (Five="1" and Ten="1") then
state_next<=statedone;
end if;
when statedone=>
state_next<=idle;
end case;
end process;
process (state_reg)
begin
Ten_Deposited<="0";
Five_Deposited<="0";
case state_reg is
when idle=>
Ten_Deposited<="0";
Five_Deposited<="0";
done<="0";
when statefive=>
Five_Deposited<="1";
when stateten=>
Ten_Deposited<="1";
Done<="0";
when statedone=>
Ten_Deposited<="1";
Five_Deposited<="1";
done<="1";
end case;
end process;

Thanks, NapDynamite. However, you just included your Project (not the actual VI) on the attachment. A good way to include all of the dependencies is to create a source distribution (LLB). 
Right-click on Build Specifications, select New»Source Distribution
Under Distribution Settings, select Custom as your Packaging Option
Check the Destination is LLB box and click OK on the warning.
Choose the Destination Path where you would like the LLB to be saved
Click Build to create the LLB, or click OK to save the Build Specifications.
