One more thing you can try:

replace all m_from with alltrim(substr(m_from,atc(";",m_from)+1))

BTW, I just noticed there was something "different" about the double quotes you used.
Yours look different (x=atc(“;”,m_from)) than mine "". Strange! We'll see if it looks different when I post this. They don't look different when posted but yours has the high bit set (yours is ASCII value 147, and normal quotes are ASCII value 34). Maybe related to your problem?


PS:
It help others to follow if you at least "quote" some of the previous message.

Sorry, Fred - You are correct about posting the message. I am typing in word and pasting here – meanwhile forgetting my manners. The appearance of the quotes is probably due to Word.

Took a minute here to try your suggestion -

Thanks for not giving up. You have earned a gold star and my gratitude! Of course I've already heard one " That's the way I would have done it." from one of the folks who couldn't figure it out earlier.

So . . what do you think was happening with good old "x"?
