When I want to quote a particular part of somebody's post, how do I do this? Each time I try, I get their entire post .

1) First I hightlight the line/s I want quoted.
2) Then I hit quote box
3) It sends me to the posting box, but the entire post is there instead of what I hightlighted. Am I doing something wrong?

I keep doing it over & over...same results

TIA tulips
