Good for you... I really don't know what you are trying to prove by continuing with this attack on me starting the thread. Surely it isn't down to you to tell me what I understand and what I don't. I felt I needed to post and while you may have felt that previous posts/threads adequately explained the situation I did not... hence my post.

Why continue to try to convince me that I shouldn't have posted? I felt I wanted/needed to ask and so as a forum member I did. If you don't think you can personally contribute to this thread then don't post but please let those that can/want to help do so. Dissuading people from making legitimate posts or asking legitimate questions is, IMO, against the spirit of the forum.

This is my last post to this thread as I do now feel I understand the situation. Thanks to all those that helped
