I replied, but now I don't see my follow-up question, explaining that the second formula doesn't seem to work. Did you get that Reply?
Yep--error in your formula was what was wrong, and so now it works perfectly.
Thanks a bunch!
I just rated you Excellent. I normally put in a tip, but didn't because I have an outstanding question with this website's managers: I found two charges on my credit card statement that were larger than the tips I checked off, and want to know why before I tip again.
If you know the "answer" to that, let me know!
