Can't Blink 2 LEDs

I am trying to blink 2 LEDS, like the railroad cross signal, but can't get it to work on a 12f629. I need to use the codes defined at below, which will make reassigning variables for other purposes easy. When I run this, only the "LEDBottom" blinks, which is that last one that the code executes. LEDTop stays on permanently. Can someone help?

Here's what I have:

'set input/output pins
TRISIO = %111100 '1=input, 0=output

'define variables
LEDTop var GPIO.0
LEDBottom var GPIO.1
TurnOn var byte
TurnOff var byte

'set variables
turnon = %0
turnoff = %1

'start of program
LEDtop = turnoff
Ledbottom = turnoff

InputLoop:
ledtop = turnon
ledbottom = turnoff
pause 500
ledtop = turnoff
ledbottom = turnon
pause 500
goto inputloop




P.S. I don't want to use this:
InputLoop:
GPIO=%000001
pause 500
GPIO=%000010
pause 500
GOTO InputLoop

Hi,

May be just

Code:
