Orange - wow!!!!
Your modification is a SIGNFICANT improvement. With the undesired characters (comma, periods, etc.) my actual raw data set contained nearly 4,200 keywords.
W/ your additional cleanup, an additional 1000 words were removed and I'm left with 3,207 keywords. BRILLIANT! That's is tremendously beneficial.
I wish to thank both of you for your superb expertise. I'll keep you posted on the next steps!!
