Koolaid -
Your thread was actually more helpful to me, as it stated things simply and clearly. (Barb's post didnt quite go into the same detail, unless I missed later posts that did)
Your thread was also simple.
Thanx
Only a Jdub would accuse you of having selfish motives for reposting this info... Seen it on here soo often over the last eleven years. Same thing happens to Leo - she posts her research because she "craves the praise and admiration of men", not because she is eager to promote knowledge and informed comment.
