Thank you for the thoughtful--and respectful answer to my question. i mistakenly asked this question on a different thread, as you have observed, and was ririculed for asking it. That is childish.
I DON'T know all of the social mores here, but RTFM.is not a polite answer. I appreciate your taking the time to tell me that what I was attempting to do does not, in fact, work--and then providing me a workable alternative.
Since I started this thread, I agree with you that as a greenhorn here,
i may be asking questions the apparent moderator has been asked before. The way I ended up on the previous theead was by looking for the answer first, and fate leading me to that page, on which I wish I'd never seen.
We look to our teachers for answers, not ridicule for being students, trying to learn from the masters.
Thanks again for being civil to me.
