Using the FS Api to save progress in RiM door, not working

I am trying to create a frame door using Redstone in Motion and computercraft. I have a program written (http://pastebin.com/TW4wMZZi) which I want to make the door move up 2 at a time in one motion, however, the door only ever moves up once and I'm not sure why. If someone could help I would be very grateful. Thanks

You can't compare a string to an undefined variable and expect it to return true :P/>

if upProgress == hello then

hello --this

"hello" --is not the same as this

That was an attempt to fix it when the string wasn't comparing to the string, even when the comparison should be correct, it doesn't move the two blocks

Wouldn't it be easier to use a For loop? an example:

file = fs.open("upProgress", "w")
for i  = 1, 2 do -- i starts at 1, increases by 1 each time the loop runs.  If i == 2 then the loop will stop
 file.write( i - 1 )
 file.close()
 drive = peripheral.wrap("left")
 drive.move(1, false, true)
end

For loop won't work. RiM platforms makes the computer reboot when it moves, hence the need to save it's state everytime.
