had a nice long chat with steve dean. clarified the points i needed and got some other gems to use. hopefully should be ok now.
what people need to realise is that although these can appear to be dumb questions, i am dealing with people who are looking fir problems, advised and misinformed by outside people who also have no idea what they are talking about. i was asked specific questions to which, as someone point out the answer is how long is a piece of string due to variables.
as most of you know im NOT new to this, but when dealing with official people, its always best to clarify the question first, to give an answer based with facts and figures.
