merlin2049er Well-Known Member Licensed User Longtime User Aug 27, 2013 #1 I had attempted to use a list (several lists) to keep variables I needed to keep track of. These variables are also in a string in one of my listviews. I was running into index out of bounds errors... when going back a few steps. Anyways, would it be just as good to parse last string in list view and roll them back. I'm not sure what the most pleasant looking way to do this is.
