It doesn't sound like your error is necessarily what you think it is. That
error happens when you do something like:
  a = [1, 2, 3, 4, 5]
  i = nil
  a[i]

You can convert most objects (including nil) to an integer with the to_i
method, but that probably isn't going to fix anything.  nil.to_i is always 0.

Post some code and someone here will likely be able to spot your error.
