ioo am not sure exactly of how you store data in your file but if it is an array I suggest using ipairs http://www.lua.org/pil/7.3.html.
If you have more question about computercraft coding I suggest the computercraft forum where more people might be able to help.

You need to make your FOR loop use the same syntax as the syntax I posted. Good luck!
