First timer...building a remote controlled vehicle

[mackrackit]

Have one side of the button connected to 5 volts, the other to the PIC pin. Have a 10 k resistor connected to the same PIC pin and ground (zero).

When the button is pushed ( assuming it is NO ) the PIN pin will be forced HIGH, that is 1.

IF PORTA.1 = 1 THEN LABEL

Being this sounds like a school project, can you tell me why the below worked?

SERIN2 PORTC.1,396,[WAIT("9"),STR MOVEMENT\2]

[.n0rig.]

I am assuming that it "waited" to receive a digit of 9, then the array of 2 movement split the next 2 incoming bytes into the array.

That part worked if afterward I did a check on what digit was sent (in this case, a 1), and then if it was a 1, to turn the pin porta.1 high. This worked and turned an LED i had put there on. Buttttt, when I did the same thing with the following if then statements...it did not work:

;lets get moving!
checkdirection:
;forward and backwards
if direction = 0 then
goto checkturns 
if direction = 1 THEN 
goto forward
if direction = 2 then 
goto backward
endif
endif
endif

checkturns:
;forward and backwards
if turns = 0 then
goto start 

start_turn: 
if turns = 1 THEN 
goto turnleft
if turns = 2 then 
goto turnright
endif
endif
endif
goto start

;left and right turns
forward:
if turns = 0 then
goto forwardgo
if turns = 1 THEN 
goto forwardleft
if turns = 2 then
goto forwardright
endif
endif
endif

forwardgo:
high forwardl
high forwardr
pause 500
low forwardl
low forwardr

goto start

I am not sure why it would not work...
