She is investigating the documentation and will respond to you promptly. With regard to future work on modeling, in order to expedite communications, I suggest you communicate directly with Cathie and Chartie on this issue. Particularly since I will be travelling for the next several days. If there is anything that I can do to help, please let me know. Thanks EID747617
