Hey R.D. Thanks a bunch for the tip. I had used this method earlier but I kept getting error. I had narrowed it down to the !=. The selectbyattributes where clause does not like that operator for NOT EQUALS, which is weird, because I have used it in other SQL queries in python.
After your post, I finally clued in to use <> and that works perfectly. Sometimes it's nice to just have someone jog your memory!
