Ah, a pivot table. A concept I've read about in passing over the years and have zero understanding of its purpose and use (hence, my passing over your previous mention of same).

I'm not looking for you to be my personal tutor--you've already been great.

I'd just like a link to what you would consider to be a concise and clear explanation (I've gotten befuddled too many times by 'explanations' written by engineers <g>).

Thanks,

Mark
