That is exactly what i have been trying to work out..
Thank you for doing it for me.. I will have to give it test (its sunday today and my girlfriend is soon going to be pissed off of i dont leave the computer alone !!)
Thanks again, i really appreciate it, Its more complivated than i imagined but I could mentally that the relationship was defined mathematicaly but just could get my head around why the calculations i had tried would work.. I always say I do this job becuse my favourite subjects at school were art and maths …. probably i liked art better though
Cheers Steve (and all you cow peoples )
