I am not sure what went wrong the first time (I checked every at the time when I reported it not working), but based on the above, I decided to test it again (hoping to spot why it worked in a MessageBox but not on a worksheet) and lo-and-behold, now it is working. I cannot explain why it didn't work the first time, but I can confirm it does in fact work for that text string (haven't tested any others yet, but I wanted to get this correction out there hoping to save you some investigation time. Sorry for the earlier misdirection.
