Agreed. What I put in was a hack.
I think when there was no P tag, string.split(";",WoWPro.prof[k]) was trying to split nil, and things went bad.
I had not finished decoding the logic there, hence my change.

Plus, I think my lua interpreter was returning different answers than was WoW's lua, so I was most confused.
