Considering sg is not defined anywhere in the script, I would expect an "attempt to index ? (a nil value)" error. I'd guess you haven't posted the full code, nor the full error.
If the error you reported does occur on the line specified, I can only conclude the "sg" peripheral (whatever it is) doesn't have a getState() method (maybe it's not the right peripheral?)
This is what is in the controller/PC

I am using a SGCraft script on the forum from 2014 from:
http://www.computercraft.info/forums2/index.php?/topic/17032-sgcontrol-sgcraft-stargate-controller/ the following. I just don't see a way to get it working and I might be mistaken but I don't see any newly updated SGCraft control scripts for the latest 1.7.10 computercraft.
