I hope I didn't put you off. Many times, I get responses stating that I am
wrong, and it can annoy. Sometimes it is because of my lack of knowledge,
and other times, the posters are just trying to show off their greater
knowledge. Why I keep posting can be a mystery, but it might be because
occasionally, as I did today, I get a response "Thank you Trevor. That is
exactly what I was looking for."
In this particular case, I am just saying it is not always as easy as it
sounds and people like Murray, who have great experience, also say the same.
To add to the relevance of my comments, I did not actually keep the original
post so I was reading between the lines.
But, if it works, as you say it does, then my misgivings are unfounded.
Please do keep posting and not just lurking.
BTW,
I have learnt a lot (not yet "everything") from this group.
