I don't know how you set "I" in your modified code - so I cannot comment on this.

As per my understanding, the initial error that you were facing has been resolved by following @Torsten's inputs. And now you are getting the following warning: (I am assuming that you have defined the variable "I", and then you are getting this warning)
